Abstract
The bidirectional insulating DC-DC converter shares high/low voltage terminals, a cooling passage, a housing, and a control board, and two independent step-down circuit () and step-up circuit () are formed in parallel to perform a bidirectional DC power conversion. A high voltage applied from a high voltage battery HV is stepped down through the step-down circuit () and output to a low voltage battery LV. On the other hand, a low voltage applied from the low voltage battery LV is stepped up through the step-up circuit () and output to the high voltage battery HV. The step-down circuit () is formed as an active clamp forward converter circuit, and the step-up circuit () is formed as an active clamp flyback converter circuit.
