Abstract:
1. An oscillator for synchronizing and controlling a multi-phase, interleaved power supply system having a plurality of power supplies providing power to a load, each of the plurality of power supplies being energized out-of-phase with every other power supply of the plurality of power supplies, the oscillator comprising: a first oscillator, having a pulse generator and electrically coupled to a first timing capacitor, that provides synchronizing, out-of-phase switching signals to one or more first power supplies; and a second oscillator, having a pulse generator and electrically coupled to a second timing capacitor, that provides synchronizing, out-of-phase switching signals to one or more second power supplies; wherein each of the pulse generators is structured and arranged to transmit a synchronizing pulse of a magnitude sufficient to exceed a pre-determined maximum voltage threshold of the other oscillator.
