Abstract :
A ZVS bi-directional DC-DC converter for high-low voltage conversion is analyzed in this paper. A novel control scheme adopting one port voltage regulated and another port current regulated is proposed to realize the energy conversion in bi-directional freely. A start-up circuit is presented for eliminating the surge current in boost mode. The operation characteristics and parameter design are analyzed in detail. A prototype rated 100 W 10 V/100 V bi-directional DC-DC converter adopting the proposed circuit and control scheme is tested
