Power Electronics Engineer
Power Electronics Engineering sits at the exciting intersection of physics, electronics, and the global energy transition. If you are the type who thinks about how a solar panel's variable DC output becomes stable grid-quality AC, or how a motor drive extracts maximum torque efficiency from an inverter, and you want to spend your career solving those problems — this is an extraordinary niche. Internationally, it is one of the best-paid technical engineering disciplines. Locally the market is small but remote work opportunities are real for those with proven skills and a strong portfolio.”
About This Role
Develops circuits that convert and control electrical power for EVs, solar inverters, and high-tech gadgets.
A Day in the Life
Design and develop electronic systems that efficiently convert, control, and condition electrical power — including inverters, converters, motor drives, and battery management systems for renewable energy, EV, and industrial applications.
- Design DC/DC and DC/AC power conversion circuits — buck, boost, H-bridge topologies
- Simulate power electronics circuits using SPICE, MATLAB/Simulink, or PLECS
- Select and specify power semiconductors — MOSFETs, IGBTs, SiC/GaN devices
- Design gate drive circuits and control algorithms for switching converters
- Design and test magnetic components — transformers, inductors, coupled inductors
- Perform thermal design and management — heatsink sizing, thermal simulation
- Build and test prototype converters — oscilloscope measurement, efficiency characterisation
- Write embedded control firmware (C/C++) for DSP or microcontroller-based power controllers
Work Environment
Electronics design lab and office environment. Power electronics engineers in Sri Lanka are primarily in the renewable energy sector (solar inverter R&D, battery storage), electronics product development companies, and increasingly in electric vehicle charging infrastructure projects. The field is highly technical and internationally oriented — many Sri Lankan power electronics engineers work remotely for European, US, and Australian companies or in academia.
Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime
Prototype and product launch phases can require intensive lab work. Generally good work-life balance in R&D environments. Remote work for international companies offers flexibility.
