Power Electronics
Power Electronics is a specialized field that deals with controlling and converting electrical power. Think of it like a translator for electricity - it changes electricity from one form to another to make it usable for different devices and systems. This field is crucial in everything from household appliances to electric vehicles to renewable energy systems. When candidates mention Power Electronics experience, they're typically talking about working with devices that control voltage, current, and frequency of electrical systems to make them more efficient and reliable.
