A system for balancing a voltage in a solar cell substring in a first solar cell panel includes an inductive balancer circuit. An inductive balancer circuit includes a first power stage pair and a second power stage pair each coupled to a solar cell substring and including: a pair of switches arranged in series; a pair of capacitors arranged in series and connected in parallel with the first pair of switches; and an inductor disposed between the first pair of switches and the first pair of capacitors. The system also includes a controller coupled to the inductive balancer circuit and configured to: oscillate a state of the pair of switches at a duty cycle; balancing the voltage across the first power stage pair and the second power stage pair; and generating a total voltage output that is a multiple of the nominal operating voltage of the most illuminated solar cell substring.

    一种用于平衡第一太阳能电池板中的太阳能电池子串中的电压的系统包括电感平衡器电路。电感平衡器电路包括各自耦合到太阳能电池子串并且包括以下项的第一功率级对和第二功率级对:串联布置的一对开关;串联布置的并与第一对开关并联连接的一对电容器;以及被布置在第一对开关和第一对电容器之间的电感器。系统还包括控制器,控制器耦合到电感平衡器电路并被配置成:以占空比振荡一对开关的状态;平衡跨第一功率级对和第二功率级对的电压;以及生成总电压输出,该总电压输出是被照射最多的太阳能电池子串的标称工作电压的倍数。
