The inverter is not using pulse-width modulation; instead, it is just producing a square-wave output into a series RLC load. If the resistance of the load is 3 ohms, the inductance is 10 mH, and the capacitance is chosen so that the resonant frequency is 10 Hz, then plot the steady-state current waveform in the load. 6.2) A single-phase, full-bridge, pulse-width modulated inverter is used to drive an RL load. The DC voltage is 310 V. Assume the carrier is a triangle wave that varies, from a minimum of zero and a maximum of one, with a relatively high frequency. Choose a duty cycle command that will produce a load voltage of 150 Vrms at 45 Hz. 6.3) Repeat 6.2) for a three-phase inverter with a wye-connected load.
