For the following circuit assume RL-12 Q and Vs-215 V. Consider the IGBT has 1.24V on-state voltage drop, 2.2mA leakage current, TSW (on)-3.36 usec and TSW (off)-2.94 usec, assume switching frequency is equal to fs=23.5 kHz, and the switching duty cycle is 30%. RL VS fs Calculate the ON-state power (conduction) loss.
