Question:medium

In IGBT an improved Miller feedback effect is seen (compared with MOSFET) because, ratio of gate-collector capacitance to gate-emitter capacitance is

Show Hint

To prevent accidental turn-on from the Miller effect during fast $dv/dt$ transitions: - Keep the feedback capacitance (\(C_{gc}\) or \(C_{gd}\)) as low as possible. - Keep the input capacitance (\(C_{ge}\) or \(C_{gs}\)) relatively high. Therefore, a lower ratio of feedback capacitance to input capacitance improves performance.
