Power electronics design is the engineering of circuits that convert and control electrical energy using semiconductor switches, such as DC-DC converters, inverters, motor drives and battery chargers. It involves choosing a topology (buck, boost, flyback, LLC and others), sizing switches and magnetics, designing the control loop and gate drive, and managing losses, heat and EMI. Safety isolation, protection against overcurrent and overvoltage, and validation across line, load and temperature complete the design.
Silicon carbide (SiC) and gallium nitride (GaN) are wide-bandgap semiconductors that switch faster and with lower losses than silicon MOSFETs. SiC suits high-voltage, high-power designs such as EV traction inverters, onboard chargers and solar inverters, typically rated from 650 V to 1200 V and above. GaN excels at lower voltages, commonly up to 650 V, and high switching frequencies, enabling compact chargers and power supplies. Both need careful gate drive and layout, because fast edges amplify parasitic inductance and EMI.
The switching frequency of a power converter is a trade-off between component size and losses. A higher frequency shrinks inductors, transformers and capacitors, but increases switching and gate drive losses and pushes more energy into higher EMI bands. Designers also place the frequency with EMC limits in mind; some choose a fundamental just below 150 kHz, where CISPR conducted emission limits begin. Spread-spectrum frequency modulation is another way to lower the peak emissions measured by the receiver.
Power supply and converter design is shaped mainly by the safety standard of the end product, such as IEC 62368-1 for audio, video and IT equipment, IEC 61010-1 for measurement and laboratory equipment, or IEC 60601-1 for medical devices. These standards define insulation levels, creepage and clearance distances, touch current limits and single-fault tests. Isolation requirements affect transformer construction, the choice of optocouplers or digital isolators, and PCB spacing, so they must be known before layout begins.
Thermal design in a power electronics stage is validated by comparing calculated losses with measured temperatures under worst-case conditions. Engineers estimate conduction and switching losses, derive junction temperature from datasheet thermal resistances and heat sink performance, then verify on hardware with thermocouples or a thermal camera at maximum load and maximum ambient temperature. The remaining margin to the rated maximum junction temperature in the datasheet drives derating decisions, heat sink sizing and, if needed, a change of device.
