Question: A MOSFET is operated as a chopper switch at a frequency of f_s = 50 kHz. The circuit arrangement is shown in Figure. The dc input voltage of the chopper is V_s = 30 V and the load current is I_L = 45 A. The switching times are t_r = 60 ns and t_f = 25 ns. Determine the values of

(a) L_s

(b) C_s;

(d) R_s if the discharge time is limited to one-third of switching period;

(e) R_s if peak discharge current is limited to 5% of load current; and

(f) power loss due to RC snubber p_s, neglecting the effect of inductor L_s, on the voltage of snubber capacitor C_s. Assume that V_CE(sat) = 0.
