IGBT Overcurrent and Short-Circuit Protection in Industrial Motor ...

Web1 dag geleden · Some of the trade-offs in enhancing insulated gate bipolar transistor (IGBT) conduction loss are increased short-circuit current levels, smaller die size, and reduced thermal capacity and short-circuit withstand time. This accentuates the importance of the gate driver circuit and its overcurrent detection and protection features. WebConduction Loss Conduction loss is calculated between Section A and Section B of the waveform in Fig. 2. In Section A, the high-side MOSFET is ON and the low-side MOSFET is OFF. Therefore, conduction loss can be calculated from the output current, on- resistance and on-duty cycle.
