Abstract
The objective is to provide a highly efficient and low-noise non-isolated bidirectional DC / DC converter while keeping costs and size increases to a minimum. [Solution] The present invention is an H-bridge type bidirectional DC / DC converter comprising a switching circuit 10 connected in series with two switching devices, a switching circuit 20 connected in series with two switching devices, and a choke coil L1 connecting the connection points of switching devices (S1, S2) and the connection points of switching devices (S3, S4), further comprising a capacitor Ca connected in parallel with switching device S2 of switching circuit 10, a capacitor Cb connected in parallel with switching device S3 of switching circuit 20, and a capacitance addition means for increasing the total capacitance of the capacitors of the switching circuit on the side where DC is output for any period of time by an additional capacitance.
