How does current flow in IGBT?
How does current flow in IGBT? Also the IGBT is a unidirectional device, meaning it can only switch current in the “forward direction”, that is from Collector to Emitter unlike MOSFET's which have bi-directional current switching capabilities (controlled in the forward direction and uncontrolled in the reverse direction). Why diode is connected across IGBT? We know that MOSFET or IGBT is a unidirectional device, they only conduct current in forward bias and block the current in reverse bias. This reverse voltage may damage the MOSFET. For this reason, an external diode is connected across the MOSFET or IGBT or SCR...
