摘要
该文基于双LCL拓扑电路提出了在副边电路增加两个开关和一个附加电容的方法,实现单个逆变器对多个电动自行车充电,且不同充电电流的电动自行车可以共享充电桩,提高充电桩的使用率。通过切换开关和附加电容可改变谐振电路拓扑,实现恒流或恒压输出的相互转换。此外,该方法还具有以下明显优点：无需原副边通信和复杂的控制电路,系统复杂性低,几乎没有无功输入。为了验证该方法的有效性和可行性,该文搭建了充电电压48V、充电电流分别为2A和4A的实验原理样机,实验结果表明该方法满足上述要求且能够提高充电桩的使用率。
Based on the double LCL topology circuit, a multiple-electric-bicycle charging method with a single inverter is proposed to meet various charging requirements by adding two switches and an additional capacitor in the secondary circuit, so that a single charging stand can charge various charging-profile bicycles. Constant current or constant voltage output can be realized by switching the switches to change the topology of resonant tanks. Furthermore, this method has the following advantages： no communication link between primary and secondary circuits needed, low complicated control circuit and system complexity, nearly no reactive power required. In order to verify the effectiveness and feasibility of the method, this paper sets up two experimental prototypes with charge voltages 48V and charge currents 2A/4A, respectively. The experimental results show that the method can meet the above requirements and improve the utilization rate of the charging stands.
