Abstract
A method of controlling a rectifier includes receiving a gain factor, receiving a ramp interval, and generating a rectifier switch control voltage. The rectifier switch control voltage is an over-modulated rectifier switch control voltage generated by a pulse width modulator using the gain factor. The amount of over-modulation in the rectifier switch control voltage is decreased during the ramp interval for reducing transient voltage overshoot events at the start of active rectification.
