Power Electronics and Control Skills That Run Modern Industry
By vaayaa Editorial Team · Subject panel: Hiroshi Tanaka (PhD, Computer Science), Carlos García (Master's, Data Science)
These eight courses share one theme: the engineering of converting, controlling and supervising electrical energy and motion, from the converter and the feedback loop up to plant-wide distributed control and SCADA supervision.
Key takeaways
- Power electronics converts and shapes electrical energy; control engineering decides how that conversion behaves.
- Batteries, variable frequency drives and motor control apply both skills to storage and motion.
- Motion control adds precise position, speed and torque coordination to automation.
- DCS and SCADA supervise whole plants and infrastructure, so operations and security skills matter as much as control theory.
- Employers list modeling, simulation and converter control as core requirements in power electronics roles.
- Electrical engineering graduates are reported to show deficits in power electronics, control systems and automation.
A wind turbine, an electric car, a conveyor line and a water treatment plant all rely on the same underlying discipline. Electrical energy arrives in one form and must leave in another, at the right voltage, frequency, torque or speed. Something must measure what is happening and correct it. Something must watch the whole plant and let people intervene safely.
That chain runs from power electronics, which switches and converts energy, through control systems engineering, which designs the feedback that keeps the conversion stable, to batteries, drives and motor control, which apply it to storage and motion. At the top sit distributed control systems and SCADA, which supervise processes and infrastructure.
This discourse explains what each skill is, where it is used, what tasks and tools come with it, and how to sequence learning across the eight areas. It is written so a reader can use it without taking any course, though each course is the natural next step for its area.
Power conversion and the control loops that keep it stable
Power electronics is the discipline of converting electrical energy with switching devices rather than with mechanical or resistive losses. Rectifiers turn alternating current into direct current, inverters do the reverse, and DC to DC converters change voltage levels. Control systems engineering supplies the feedback theory that decides how fast, how stably and how accurately each converter responds.
The Power Electronics Systems course covers conversion topologies, switching devices and the way energy moves through a system. The Control Systems Engineering course covers modeling, stability and the design of controllers for dynamic systems. Together they form the base layer for every other topic here.
Typical tasks and tools
Job descriptions for control design engineers at Hitachi Energy describe planning control and protection for converter projects, simulating converter behavior during grid disturbances, and verifying software on real-time simulators and project hardware [1][7]. A Schneider Electric role for control system design lists pulse width modulation strategies for three phase inverters, current control, DC voltage control and active or reactive power control as hands-on requirements [5][8].
Fact A GE Vernova lead engineer role in power electronics asks for modeling, simulation, design and testing of converters, plus hardware-in-the-loop testing of advanced electrical controls [3].
All three named electrical engineering deficits fall inside the areas covered by these courses.

Energy storage and the safe management of battery packs
A battery management system measures cell voltage, current and temperature, estimates state of charge and state of health, balances cells and protects the pack from abuse. It is the layer that makes a battery pack usable in an electric vehicle, a grid storage container or a portable tool.
The Battery Management Systems course covers these functions, along with the safety, reliability and performance requirements that storage applications place on the pack. It connects naturally to power electronics, because the charger and the inverter are the battery's interface to the outside world.
Where battery management appears
A power electronics engineer role for electric vehicles lists battery management systems alongside inverters, converters, control algorithms and compliance testing [4]. That overlap is typical: storage work and conversion work share the same control vocabulary.
Opinion A learner who understands both converter control and battery limits is more useful on storage projects than one who knows only one side of the interface.
Electrical engineering sits below electronics and computer science in reported employability, with power electronics and control named as its deficits.

Drives and motor control for efficient industrial motion
A variable frequency drive adjusts the voltage and frequency fed to an AC motor so the motor runs at the speed the process needs. The Variable Frequency Drives course explains how drives move motor control from simple on and off switching to precise speed and torque regulation, and where energy savings come from.
The Motor Control Systems course widens the view to motor control systems as a whole, including starting methods, protection, feedback devices and integration with automation. Industrial automation depends on this layer: conveyor belts, pumps, fans and robotic joints all need a controlled motor behind them.
What the work involves
Hitachi Energy notes that its power conversion team has built what it describes as the world's largest drive for a hydro pump station, which shows how far drive engineering scales [1][7]. At the other end, a single pump in a building services plant uses the same principles.

Motion control, DCS and SCADA across the plant
Motion control coordinates several axes so a machine performs a precise sequence: positioning, synchronization, electronic gearing and cam profiles. The Motion Control Technology course covers the principles and practices used in industrial motion systems, from single axis positioning to coordinated multi axis work.
Above the machine level sit distributed control systems. The DCS Technology Management course treats DCS as a technology management problem: controllers, input and output modules, networks, historians, alarm management and lifecycle change control across a process plant. The SCADA Systems Operations course covers SCADA operations for monitoring and controlling infrastructure, where reliability, operator procedures and network security are central.
Tasks, roles and tools
Control design roles at Hitachi Energy include SCADA and HMI application development, faceplate and popup creation, and design of a secured network architecture for converter projects [1]. SCADA knowledge is therefore useful even to engineers whose main work is power conversion.
Fact IRENA-linked analysis of renewable energy jobs identifies digital monitoring and SCADA, battery storage and power electronics among newer skill requirements, and lists inverter and SCADA technicians among shortage sensitive roles [15].
Comparing the three main skill areas
The eight courses cluster into three areas. Device and conversion skills cover power electronics, batteries and drives. Control and motion skills cover control engineering, motor control and motion control. Supervision skills cover DCS and SCADA. Each area has a different center of gravity, different tools and different daily outputs.
The comparison table below sets out how they differ on scope, core method, typical tools, output and the background that helps most. A reader planning a career move can use it to decide where to start rather than trying to learn everything at once.
Estimate Based on the employer requirements cited here, device and conversion roles ask most often for simulation and hardware verification, while supervision roles ask most often for network security and operational procedure.
How to start learning power electronics and control
Start with the physics and mathematics of circuits and feedback, then choose one area to go deep in. A learner with an electrical background can begin with power conversion and control theory in parallel, because each reinforces the other. A learner from automation or operations can begin with drives, motor control and SCADA, then add theory.
- Confirm your baseline in circuit analysis, Laplace transforms and basic feedback.
- Pick one anchor course from the conversion, control or supervision area.
- Build a small simulation of a converter or a control loop and change one parameter at a time.
- Add the adjacent course that explains the interface, such as batteries for a charger or SCADA for a converter.
- Keep a written record of models, assumptions and test results, because employers ask for documented design work [5][8].
The pathway below arranges the eight courses into a sequence that builds from devices to plant supervision.
Original analysis
vaayaa analysis: matching reported deficits to course areas
- Take the reported electrical engineering employability rate of 68.0 percent and its named deficits: power electronics, control systems and automation [12].
- Take the reported ratio of 3,068 power electronics job listings to 51 professionals, which is 0.02 [11].
- Map each named deficit to a course group and count how many groups are covered.
- Compare that count with the total number of course groups to see where the gap concentrates.
All three named deficit areas map directly to course groups here, so the training gap described in the sources aligns with the course set rather than with general electrical theory. The listings ratio points to a sharp reported imbalance in power electronics specifically, which supports starting with conversion and control.

Worked example
Estimating duty saving from a variable speed pump
- Assume a 15 kW motor running continuously at full speed.
- Assume the process needs 70 percent of full speed for most of its duty.
- For a centrifugal load, power varies roughly with the cube of speed, so 0.70 cubed is 0.343.
- Reduced shaft power is 15 kW multiplied by 0.343, about 5.1 kW.
- Allow 10 percent for drive and motor losses, about 0.57 kW, giving 5.7 kW.
- Subtract from the original 15 kW to get about 9.3 kW saved during that duty period.
About 9.3 kW of approximate duty saving, valid only under the stated assumptions about load type and duty. Verify against measured operation before relying on it.
Starting checklist for a power electronics and control learner
- Confirm baseline skills in circuits, transforms and feedback.
- Pick a starting area: conversion, control and motion, or supervision.
- Build one simulation model of a converter or control loop.
- Learn the tool your target roles list, such as MATLAB, Simulink or PLECS.
- Study the interface course that borders your chosen area.
- Document one project with model, assumption, test and result.
Frequently asked questions
Do I need power electronics before studying control systems?
Not strictly. Control systems engineering is a general discipline that applies to any dynamic system, so it can be studied first. It becomes far more useful once you can apply it to a converter, motor or drive, which is why the two courses sit naturally side by side in this set.
Where does a battery management system fit with power electronics?
The battery pack and the converter meet at a charging and discharging interface. The management system enforces voltage, current and temperature limits, and the converter must respect those limits. Learning both sides helps an engineer avoid designs that stress cells or trip protection unnecessarily.
Is SCADA work mainly software or mainly electrical?
It is both, plus operations. SCADA engineers configure point databases, telemetry and screens, and they also need to understand the equipment being monitored, the network that carries the data and the procedures operators follow. Reliability and security are part of the job description, not an afterthought.
What is the difference between DCS and SCADA?
A distributed control system is built around process control in a fixed plant, with controllers spread across the site and heavy emphasis on continuous loops, alarms and change management. SCADA is built around monitoring and controlling assets that may be spread over wide distances, so telemetry and remote operation matter more.
Which tools should a beginner learn first?
A simulation tool is the usual first step. Employer listings for power electronics roles name MATLAB and Simulink, with circuit simulators such as PLECS and LTspice appearing in related postings [2][6]. Start with one simulation tool and one small model rather than several tools at once.
Can a career changer from another engineering field move into this area?
Industry commentary on the power electronics labor market points to career changers from other industries as a source of supply [13]. The realistic route is to build the circuit and feedback basics, complete a documented project, and target roles in drives, storage or plant automation where adjacent experience counts.
Conclusion
Power electronics and control form one connected discipline. Conversion without control is unstable, control without conversion has nothing to steer, and supervision without either has nothing to watch. Batteries, drives and motor control are applications of the pair, while motion control, DCS and SCADA extend them to machines and plants.
The reported skill deficits and employer requirements point to the same conclusion: the valuable learner is the one who can model a system, design a loop, verify it, and explain it in documentation. Choose an entry point from the three areas, learn the adjacent interface, and keep evidence of your work.
