DESIGN AND SIMULATION OF A SINGLE-PHASE INVERTER WITH DIGITAL PWM _____ i . Abstract . The current project has as major aim th e design of a single -phase inverter for educational purposes. The main distinctive feature is the digital implementation of the PWM modulation. - For a smooth signal we choose phase correct pwm at a frequency 31372 Hz-see previous post. One of the biggest problem is that how we calculate the necessary duty cycle for each pulse. So, because our frequency is f=31372Hz the period for each pulse is T=1/31372=31.8 us, so number of pulses for a half cycle is N=10ms/31.8us=314 pulses.
