Abstract

A system and a method for to use multiplepower sources for supplying power to a load. The system and method use a triggering system to automatically and substantially cancel a ripplecomponent of the input current drawn by the system. A master power source and a slave power source supply power to the load. The triggering system results in the two power sources having switching frequencies that are substantially equal' and switching cycles that are substantially ISO' out of phase. Further, the method and the device contemplate the use of a local oscillator in the triggering system to ensure that the slave power source is triggered to the on position at a point in the switching cycle of the master power source that is approximately ISO- out of phase with a leading edge of the master switching drive signal. The system and method are advantageously wed to provide a power factor correction front-end for a switch-mode power supply. Power supplies with a diverse array of relationships between power supplied and switching frequency can be used.
