SINGLE-STAGE CONVERTER WITH CORRECTED POWER FACTOR THAT HAS ISOLATED OUTPUT.

摘要

A POWER CONVERTER THAT WORKS TO REDUCE HARMONICS AT AN AC INPUT (101,102) BY CONTROLLING ITS POWER SWITCHING SO THAT A CURRENT WAVE SHAPE IN A SWITCHED INDUCTOR (130) IS SUBSTANTIALLY IDENTIFYING A RECTIFIED VERSION THE INPUT AC VOLTAGE WAVE SHAPE. THE VOLTAGE POINTS INDUCED BY THE SWITCHING OF THE INDUCTOR IN CIRCUIT INCLUDING THE LEAK INDUCTANCE OF A POWER TRANSFORMER ARE SOFTENED BY THE CIRCUIT (144,145,112) THAT ABSORBES THE INITIAL VOLTAGE POINT (TEMPORARILY AND THROUGH OUT OF SUPPLY) 141,142) OF THE CONVERTER.
