| Abstract: | A charging power supply based on serial load resonant converter (SLRC) is presented, this paper introduces operational principle of SLRC and soft-switching characteristics. The current characteristics of converter with battery load is analyzed. The control circuit based on constant on time and variable switch cycle control strategy is proposed and the current can be constant. The scheme of interleaved module is proposed to lower output ripple current, simulation results prove the feasibility of this scheme. The prototype is developed and the experimental results indicate that the power switch has been working on soft-switching state, and the charging power supply can maintain constant-current. |
