Abstract
A high efficiency electronic load has a switch mode power factor corrected (PFC) input rectifier circuit that provides a high voltage positive and negative direct current (DC) voltage to drive a switching inverter that in turn delivers an output alternating current (AC) back into an AC power line. The input PFC circuit is phase and frequency controlled by the input AC power line which allows the input and output to be operating at completely different frequencies.
