Abstract:
1. A system for regulating alternating current (AC) power output and regulating alternating current (AC) input power factor including in combination: alternating current (AC) input terminals; alternating current (AC) output terminals; a switch-mode regulator circuit connected between the AC input terminals and the AC output terminals; means responsive to the voltage on the AC output terminals and to the voltage on the AC input terminals for producing a voltage analog sum (Vs); means responsive to the voltage (Vo) on the AC output terminals and to the voltage analog sum (Vs) for producing a feed-forward signal (FWS); a voltage error differential amplifier coupled to the alternating current input terminals and to a reference signal to produce a voltage a voltage error signal (VES); a source of clock pulses; a comparator having a first input coupled to receive the VES and a second input coupled to receive clock pulses from the source of clock pulses to produce a variable amplitude regulator signal (VAR); a switch means connected to receive the VAR and the FWS for generating a demand level control signal (DLS); and means responsive to the DLS for controlling the operation of the switch-mode regulator circuit.
