Abstract :
A ZVS bi-directional DC-DC converter for vehicular electronics is analyzed in this paper. As a kind of current-voltage hybrid converter, the converter is composed of an isolated boost converter and a bridge converter. The principle of soft switching is presented in detail. The boost inductor is designed appropriately to satisfy the ZVS for all power devices. A control scheme adopting one port voltage regulated and another port current regulated is proposed to realize the energy conversion in bi-directional freely. A prototype rated 12 V/42 V bi-directional DC-DC converter adopting the proposed control scheme is tested. The simulation and experimental results convince the high steady state and dynamic state performance of the converter.
