Abstract: A system may include a power train comprising a rectifier and power factor correction stage configured to receive an alternating current (AC) input voltage waveform and convert the AC input voltage waveform into a regulated direct current (DC) voltage on a bulk capacitor configured to store electrical charge and a controller configured to control the rectifier and power factor correction stage to perform power factor correction between the AC input voltage waveform and an AC input current waveform related to the AC input voltage waveform. The controller may implement a voltage regulation loop configured to regulate the regulated DC voltage on the bulk capacitor to a desired constant average value based on a combination of a DC current signal associated with the power train and a voltage loop error signal based on the regulated DC voltage and a current loop regulating the shape of the AC input current waveform to a sinusoidal value in phase with the AC input voltage waveform.
