(i) A chopper circuit drives an inductive load from 360 DC supply. Given the load resistance as 8 2, the average load current as 20 A and operating frequency is 480 Hz. When the chopper is ON, 7 V is dropped. Calculate (a) conduction period (in milliseconds) (b) blocking period of the chopper (in milliseconds) (c) duty cycle of the chopper (d) draw the ON and OFF time period waveform (ii) Draw the circuit diagram of the single phase bridge rectifier which is used in two quadrant operation (RL load) and explain its operation. · Duty Cycle ON period OFF period
