Title:
SINGLE-PHASE ISOLATED SEPIC CONVERTER FOR POWER FACTOR CORRECTION
Document Type and Number:
WIPO Patent Application WO/2020/027374
Kind Code:
A1
Abstract:
The present invention relates to a single-phase isolated SEPIC converter for power factor correction that can obtain a DC power supply isolated from an AC power supply by means of a single power conversion. In order to address the above issue, the present invention obtains a power factor correction function and a DC power supply isolated from an AC power supply through a single power conversion circuit, without using a full-wave rectifier diode and an additional isolated DC-DC converter, such that conduction loss and number of circuit components are reduced, and power conversion efficiency is improved.
