ELECTRIC POWER CONVERSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To stably reduce loss of an electric power conversion system.SOLUTION: An electric power conversion system according to the aspect of the present disclosure includes: a bridge circuit having a first switching element and a second switching element; a first auxiliary switch; a first auxiliary inductor; a controller; a transformer; a secondary inductor; a rectification circuit; a smoothing circuit; and an output detection circuit. When the detection value of the output detection circuit is equal to or less than a set value, the controller makes the first auxiliary switch perform an on/off operation. When the detection value exceeds the set value, the controller makes the first auxiliary switch maintain an off state.
