4. The DC source supplying an inverter with a bipolar PWM output is 250 V. The load is an RL series combination with R= 20 2 and L = 45 mH. The output has a fundamental frequency of 60 Hz. (a) Specify the amplitude modulation ratio to provide a 160V RMS fundamental frequency output. (b) If the frequency modulation ratio is 31, determine the total harmonic distortion of the load current. (20 points)
