Apparatus for minimizing peak power demand on inverter in power supply with one or more switched reactive loads

An apparatus 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 an inverter;
• and
• a bypass control device comprising:
• one or more filters for selecting one or more 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 identified frequency components of the selected load current signal;
• and
• a bypass driver for driving the AC semiconductor bypass switch configured to divert a transient load current away from the inverter for overcurrent protection or act as an actively controlled current source to supply a transient load current of a required magnitude.
