【Abstract】 A 1kW power operating supply module has been developed,the power stage is realized by employing a phase-shift control full bridge zero-voltage-zero-current-switching(ZVZCS) converter,and a current doubler rectifier is used at the transformer secondary side.All the power semiconductors in the converter are operated at a wide range soft-switching condition.The voltage and current dual close-loop feedback system is adopted and the peak-value current control mode is used.The highest automatic current sharing method is utilized to distribute load current equally among the paralleled modules,and the experiment results are also presented.更多还原
