Abstract

The flicker free switching of electrical power to a system having two part loads is based upon generation of pulses (A,B,C) obtained from the half waves of the ac supply voltage. The switching system operates with a pulse width modulation such that load switching provides power consumptions of 8,18,33,60,93 and 100% in stages depending upon the pulse supply combinations.
