Abstract
An efficient off-line rectified, high-power, AC-to-DC power supply is provided. High-power factor and minimal circuit size, cost, and complexity are achieved by combining switchmode power converter operation as well as conduction-mode operation. The switchmode power converter is controlled such that only a fraction of the output power is converted by the switchmode power converter. Peak power is efficiently conducted directly from an AC line to a DC output without requiring the operation of the switchmode power converter. Such control method results in high efficiency, yet also maintains a high-power factor with optimally sized, cost-effective switchmode power converter electronics. A complete, self-contained system is provided including a soft-start, full-wave bridge.
