Abstract
An apparatus is provided for minimizing the peak power demand on an inverter in a power supply with one or more switched reactive loads comprising an AC semiconductor bypass switch connected in parallel with the inverter and a bypass control device. The bypass control device includes filters for selecting load current signals with specific frequencies of interest from the switched reactive loads; a signal processor for sampling and transforming the selected load current signals into frequency domain to identify frequency components of the selected load current signal; an amplitude detector for detecting peak current amplitudes of the identified frequency components of the selected load current signal; and a bypass driver.
