FLYBACK AC-DC CONVERSION DEVICE AND CONVERSION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/078095
Kind Code:
A1
Abstract:
A flyback AC-DC conversion device and a conversion method thereof. The device contains a rectifier circuit (R), an electronic switch (SW), a flyback transformer (10) and an automatic charge pumping circuit (20), wherein the flyback transformer (10) is provided with a primary side and a secondary side, wherein the primary side is electrically connected to the rectifier circuit (R) and the electronic switch (SW); and one side of the automatic charge pumping circuit (20) is electrically connected to the secondary side of the flyback transformer (10), and the other side thereof is electrically connected to a load (200), so as to improve the conversion efficiency of a power source and be capable of restraining the ripple of an output voltage. Additionally, further disclosed is a power source conversion method for the flyback AC-DC conversion device.
