Abstract :
Low-voltage on-board DC-DC converters are increasingly required to have high efficiency and fast transient response. In this paper, two-stage DC-DC converter architecture is proposed to achieve fast transient response while operating at high efficiencies, which feature soft switching, self-current-sharing capability and simplified self-driven techniques for the synchronous rectifiers.
