A bridge PWM inverter should provide alternating voltage at a frequency f = 50 Hz across an RL load (R = 10 Ω, L = 20 mH). The amplitude modulation factor is ma = 0.8 and the frequency modulation factor is mf = 21. The input DC voltage is VDC = 100 V. Determine power dissipated in resistive component of the load?
The output voltage of a single-phase full wave bridge voltage source inverter is controlled by unipolar PWM with one pulse per half cycle. For the fundamental rms component of output voltage to be 75% of DC voltage. What is the required pulse width in degrees?
