uestion (oDo Choppers 6 marks A 2-quadrant chopper circuit shown below is used to control the DC motor speed and for regenerative braking. The motor constant is КФ-0.1 V/rpm. The chopping frequency is 500 Hz. The motor R 0.2 ohm. The inductive La is sufficiently enough and the motor current can be assumed ripple-free. The supply voltage is 240 V. A In motoring, chopper switch T1 and D2 operates to control motor speed. At N-400 rpm and motor current io- 100 A (ripple free) i. Determine duty cycle of the chopper (or Tom) ii. Determine power developed by the motor, power absorbed by the Ra and power from 2 marks the source 12 marks) In regenerative braking, chopper switch T2 and D1 operates to break the motor speed.
