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 process is at 95% efficiency. Below you are required to refresh your understanding of AC to DC rectifiers. Diode rectifiers are non-linear loads so grid power factor and harmonic generation are again a consideration. The total power factor is composed of two parts: the distortion power factor due to...
