Design an inverter that has a PWM output across an RL series load with R = 30 Ω and L = 25 mH. The fundamental frequency of the output voltage must be 100 V rms at 60 Hz, and the total harmonic distortion of the load current must be less than 10 percent. Specify the dc input voltage, the amplitude modulation ratio ma, and the switching frequency (carrier frequency). Verify the validity of your design with a PSpice simulation.
