Universal-input, high-power-factor, boost doubler rectifiers

This paper describes new universal-input high-power-factor boost doubler rectifiers (BDR). The new rectifiers can be configured for low-line (90-130 V RMS) or high-line (180-260 V RMS) operation such that component stresses and the rectifier efficiency are approximately the same for both the high-line and the low-line input. As a result, significant efficiency and size improvements can be obtained compared to the conventional boost rectifier designed for universal-input operation. Results are experimentally verified on a 220 W prototype
