Abstract
A Low-voltage DC-DC Converter (LDC) includes a new bidirectional isolated LDC, in which two converters with different power circuit topologies operate in parallel in order to enable both buck mode and boost mode. The two applied converters are a phase-shift full-bridge converter with full-bridge synchronous rectification and an active-clamp forward converter. According to the present invention, it is possible to achieve the advantages of both a phase-shifted full-bridge converter with full-bridge synchronous rectification applied and an active clamping forward converter. Thus, it is possible to minimize output voltage and current ripples, thereby improving the quality of the LDC output power while minimizing electromagnetic waves generated while a product is operating.
