FULL BRIDGE SWITCHING CIRCUIT

摘要

PURPOSE: A full bridge switching circuit is provided to have 6 switching devices whose channel is adjustable individually, by a simple method without complex control like a phase shift method. CONSTITUTION: A converter circuit part includes a first converter circuit and a second converter circuit. The first and the second converter circuit include a first and a second transformer. The first and the second converter circuit include a first and a second switching device part(SWa, SWcom) respectively. The first and the second switching device control the first and the second transformer. The first and the second transformer output a first and a second feedback signal according to the control of the first and the second switching device. A third switching device part(SWb) has a third switching input, and is connected to the first and the second transformer. An IC circuit part(102) generates a logic OR signal of a first control signal and a second control signal.
