Abstract
A power supply for use with Class D amplifiers in energy efficient applications is described herein. The power supply reduces the effects of off side charging and improves cross regulation. The topology of the power supply can be designed to minimize quiescent mode losses through resonant switching of some or all active switches. Additionally, the power supply can be implemented without external resonant inductors, the power supply can be implemented with smaller capacitors that have longer lifetime ratings, the switching losses present in a power factor correction stage of the power supply can be reduced, and/or a modified power factor correction choke can be utilized to reduce energy loss.
