What is a Power Semiconductor?
A power semiconductor is used to switch or control power (or current) in electrical circuits. These include the power diode, power MOSFET, Bipolar Junction Transistor, Thyristor and Insulated Gate Bipolar Transistor (IGBT). They can be categorised as either 2-terminal, or 3-terminal devices.
Power diodes are 2-terminal devices, made up of two type

What is an Isolated Gate Bipolar Transistor?
Before the development of the IGBT, power electronics engineers had two types of device available for higher frequency switching – the Bipolar Junction Transistor (BJT) and the Metal Oxide Field Effect Transistor (MOSFET). Both devices could switch at higher frequencies than Thyristors (or SCRs) but each had some
