Abstract

An AC-to-DC power converter configured to provide power factor correction and a single isolated low-voltage output. The power converter includes a single-stage resonant power converter including an isolation transformer, a resonant tank, a rectifier, and a bulk storage capacitor coupled to an output of the isolation transformer. In typical applications, at least one non-isolated power converter is coupled to the output of the single-stage isolated power factor correction converter.

Description

technical field [0001] The present invention relates to power converters. More specifically, the present invention relates to resonant power factor correction converters. Background technique [0002] A power supply is a device or system that supplies electrical energy or other types of energy to an output load or group of loads. The term power can refer to the main distribution system and other primary or secondary energy sources. Power conversion refers to the conversion of one form of electricity into another desired form and voltage, such as converting 115 or 230 volt alternating current (AC) supplied by a power company to regulated low-voltage direct current (DC) for electronic equipment, called for AC to DC power conversion. [0003] A switched-mode power supply, switch-mode power supply, or SMPS is a power supply that incorporates a switching regulator. While a linear regulator regulates the output voltage using transistors biased in their active region, an SMPS a...
