Abstract
The present disclosure relates to a high electric power density bidirectional isolated low voltage DC-DC converter (LDC) assembly, in which a large-capacity bidirectional isolated LDC circuit is packaged in consideration of a flow of electric power so as to use components in common and minimize an internal dead space, and a cooling structure thereof. LDC assembly includes a power board subassembly (100) including the high voltage stage, a part of the buck circuit, and the boost circuit; a transformer subassembly (200) including a transformer of the buck circuit; an output power board subassembly (300) including a part of the buck circuit; and an EMC filter subassembly (400) including an EMC filter included in the low voltage stage.
