Question

 Using the sine PWM method with the full bridge inverter below, it is desired to generate a voltage of 50 Hz on the serial RL load. A voltage of 120 V DC is applied to the input of the inverter circuit. Amplitude modulation rate ma -0.9 and frequency modulation rate mf -19. The resistance of the series RL load is 15 OHM and the coil inductance is 40 mH.

a) What is the power drawn by the load resistor?
b) What is the total harmonic distortion value (THD) of the load current?
