Description
3BHE025541R0101 ABB | Processor unit
Product technology
The mechanism of GCT without intermediate zone and buffer shut-off is that strong shut-off can make its cathode injection stop instantaneously and does not participate in the later process. When the device is switched off in bipolar transistor mode, the premise is that a very high negative voltage is applied outside the p-base N emission junction, so that the anode current quickly transfers (or reverses) from the cathode to the gate (gate reversal thyristor is hence named). Once the inactive NPN tube stops injecting, the PNP tube is easily turned off due to the absence of base current. GCT becomes PNP tube earlier than it can withstand full blocking voltage, but GTO can withstand full blocking voltage in the phase of rotation of YunCr, so GCT can operate without buffer like IGBT, without secondary breakdown, and the trailing current is large but the time is short.
