摘要
结合超级电容器端电压在储、释能过程中变化范围宽的特点,配置双向直流变换器作为接口电路,可实现充、放电功率的灵活调节,并提高其储能利用率。详细分析了双向直流变换器的拓扑结构及其功率电路的设计要点。为了充分发挥超级电容器响应速度快的优势,采用负载电流前馈实现了输入电压和负载变化的复合前馈补偿,实验结果验证了该方案的有效性。
A detailed analysis and desigen on bi-directional DC-DC converter for ultracapacitors are presented. A feedforward control channel is build which can compensate the voltage sag of ultracapacitors when the energy storage is discharging and can also enhance the transient performance of ultracapacitor energy storage. The experimental results are given to valid the suggested approach.
