Abstract
In order to improve the performance of the DC-DC converter,a new type DC-DC converter with low input current ripple and high voltage gain is proposed.Through using double boost chopper and a reasonable filter capacitance to decrease input current ripple,high voltage gain is achieved by the cooperation between the high-frequency stepup transformer and the vice-edge switch capacitance booster circuit.In this paper,the working principle of proposed DC-DC inverter and comprehensive performance of system are analyzed in detail,and detail design method of system is further given.In the end,a 100 W,20V/200V prototype has been built to validate the correctness of this theoretical analysis,by which the highest efficiency of 92.5％ is obtained.关键词
