The essence of a power device is its ability to handle high voltage while cutting off or passing high current. Unlike standard integrated circuits (ICs) that focus on processing data, power devices focus on:
: Changing electrical energy from one form to another—such as AC to DC (rectification) or DC to AC (inversion). Power Devices for Efficient Energy Conversion
: Rapidly turning current on and off to regulate power flow. The essence of a power device is its
