SERIES RESONANT CONVERTER AND SERIES RESONANT CONVERTER SYSTEM

摘要

PROBLEM TO BE SOLVED: To detect a high voltage output from a series resonant converter with high precision.;SOLUTION: An output transformer T1 steps up an input voltage input into a primary side and outputs an output voltage from a secondary side. A resonant coil L1 is connected to the primary side of the output transformer T1. A voltage detection transformer T2 steps down the input voltage input into the primary side of the output transformer T1 and outputs a detection voltage from a secondary side. A correction transformer T3 that is a transformer having a primary side connected to both ends of the resonant coil L1 and a secondary side connected to the secondary side of the voltage detection transformer T2 servers to cancel a distortion component in the detection voltage due to a leakage inductance appearing on the primary side of the output transformer T1.;COPYRIGHT: (C)2013,JPO&INPIT
