A DC series motor is powered by a DC-DC converter which is supplied from a 500V DC source. The armature resistance is 0.03 Ohms, the field resistance is 0.06 Ohms and the back emf constant is 20 mV/rad/s. The average armature current is 450A and is ripple free. The duty cycle is set to 0.8. The input power would be equal to: please chooses an answer a. 180 kW O b. None of these C. 135 kW O d. 90 kW
