| Abstract: | A scheme of phase-shifted half-bridge three-level DC/DC converter closed-loop system was proposed firstly,then designed UCC3895-controlled voltage outer-loop circuit,peak current inner-loop circuit and current compensated sub-circuit.And the small-signal model of the closed-loop system was established.Final simulation and experiment results indicate the performance of the closed-loop system is preferable,transformer has no magnetic-biasing,main power switches realize ZVS well,the whole system work stably. |
