Insulated-gate bipolar transistor - Wikipedia

An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily forming an electronic switch. It was developed to combine high efficiency with fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure.

WebOvercurrent is detected by monitoring the collector- emitter voltage of the IGBT - in normal operation the VCEvoltage drop will typically be around 2 - 3V, but this increases with increasing collector current. The Zener diode Z1 is selected to set the VCElevel at which the protection will operate. http://educypedia.karadimov.info/library/an-990.pdf
