1. Variable frequency electronic generation of sinusoids first requires the grid AC to be rectified into DC. Next the DC is converted to high f AC by an inverter circuit. The entire twostep process is at 95% efficiency. Below you are required to refresh your understanding of AC to DC rectifiers for both single and three phase AC. Diode rectifiers are non-linear loads so grid power factor and harmonic generation are considerations. The total power factor is composed of two parts: the distortion power factor due to harmonics and the displacement power factor caused by the phase shift between the grid current and grid voltage
a. Explain single phase 1/2 wave rectification to a pure resistive load and give equations for the effective DC rectified voltage and the voltage ripple on the DC. Give equations for ripple around the DC. Compare to three phase ½ wave rectification
b. Explain single phase full wave rectification to a pure resistive load and give equations for the effective DC rectified voltage and the voltage ripple on the DC. Give equations for ripple around the DC. Compare to three phase full wave rectification
