多源激励式均衡电路的设计

Design of Multi-sources Excited Balanced Circuit

针对超级电容器在串联中存在的问题,介绍了一种应用多源激励变压器原理,将多个双向推挽变换器通过一个多绕组的变压器实现相互耦合的动态均衡电路。通过能量的耦合,实现串联超级电容器组单体电压的实时动态均衡,使超级电容器组延长有效的使用寿命,提高超级电容器的工作可靠性。

Aiming at the problems of the ultra capacitors in series,a dynamic balanced circuit was proposed,which applied the principle of multi-sources excited transformer,and put multi bi-directional push-pull converter to-gether through a multi winding transformer to achieve coupling.A dynamic voltage balancing of cell voltage of ultra capacitors in series every time was achieved through the energy coupling,the lifetime of the ultra capacitors was prolonged and the work reliability was improved.
