摘要
分析了常规耗能型电压均衡电路的问题。将DC/DC变换器移植到超级电容器电压均衡中。提出间隙与迟滞结合的控制策略,得到较大范围的动态均压。利用反激式变换器实现低端超级电容器C2对高端超级电容器C1的电压均衡、变形的CUK变换器实现高端超级电容器C1对低端超级电容器C2的电压均衡。实验结果验证了文中提出的"无损耗"电压均衡电路的有效性。
The issue of the regular energy consume for the voltage balance circuit is analyzed. To obtain wide range dynamic balance voltage, both DC/DC converter and gap delay combination control mode are introduced to the ultra capacitor voltage balance circuit. The boost converter is used to achieve voltage balance from lower side ul- tra capacitor C2 to higher side ultra capacitor C1. Correspondingly, the evolved care unite skin (CUK) converter is used to achieve voltage balance from high side ultra capacitor C 1 to low side ultra capacitor C2. Experimental re- sults verify the effectiveness of zero loss voltage balance circuit.
