Question

At turn-on the initial delay or turn on delay is the time required for the

(a) input inductance to charge to the threshold value

(b) input capacitance to charge to the threshold value

(c) input inductance to discharge to the threshold value

(d) input capacitance to discharge to the threshold value

I have been asked this question during a job interview.

The question is from MOSFETs-2 in section Power Electronics Devices of Power Electronics

Answer 1

Right option is (b) input capacitance to charge to the threshold value

Best explanation: It is the time required for the input capacitance to charge to the threshold value, which depends on the device configuration. The device can start conducting only after this time.
