根据串联电容逐个充电升压、逐个取电降压的原理,提出一种新型谐振式双向开关电容变换器.谐振电感仅为一只参数很小的电感,且无须添加辅助器件,即能完成全电路的软开关.在不改变工作方式下,实现了实时双向的电能传输,传输方向仅取决于高压端和低压端的电压值.由RLC 电路谐振规律和等电量方法解得充电平均电流、传输功率、输出电压和变换效率的数学表达式.最后通过MATLAB/Simulink仿真和制作样机,进行单向模式和双向模式的实验,验证了本方案的正确性.
Based on the theory of charge voltage boost and discharge voltage buck successively for series capacitors
this paper proposes a new type of resonant bidirectional switched capacitor converter. A tiny parameter resonant inductance will comply soft-switching in the whole circuit without any other additional component. The real-time bidirectional power transmission can be implemented without the operation mode change
and the transmission direction only depends on the voltage values at the high and low ends. The mathematical expression of average charging current、 transmitted power、 output voltage and conversion efficiency can be achieved based on the resonance law of RLC circuit and the isoelectric quantity method. Finally
through the MATLAB/Simulink simulation and designed prototype
the validity of the proposal had been verified by the experiments in unidirectional and bidirectional modes.
