BIDIRECTIONAL CONVERTER CIRCUIT HAVING BATTERY CHARGING AND DISCHARGING FUNCTION

摘要

A bidirectional converter circuit according to an aspect of the present invention includes: a transformation unit which is connected to an input terminal and includes a first transformer, a second transformer, and a first switch for connecting or disconnecting the first transformer to or from the second transformer; and second and third switches which performs complementary switching on and off operations to connect or disconnect the conversion part to or from an output terminal. So, volume and manufacturing costs can be reduced.
