The invention provides a variable-structure photovoltaic electric vehicle charging pile. The variable-structure photovoltaic electric vehicle charging pile comprises a photovoltaic module, a main circuit, a control circuit and a topology selection circuit, the main circuit is used for converting photovoltaic output into controllable output under the control of the control circuit so as to supply power to a load; the main circuit is provided with two conversion topologies with different voltage gain ranges; and the topology selection circuit obtains the output converted by the main circuit, compares the current output value with a reference value, and selects the conversion topology corresponding to the voltage gain range according to the magnitude relationship between the current output value and the reference value. The charging pile has two working topologies and has a wide voltage range. Meanwhile, different topological structures are selected to meet the load requirement under the condition that the load and the input are changed, and high adaptability is achieved.
本发明提供了一种变结构光伏电动汽车充电桩,包括:光伏、主电路、控制电路和拓扑选择电路;主电路用于在控制电路的控制下将光伏的输出变换为可控制的输出,以便为负载进行供电;主电路设置有两个不同电压增益范围的变换拓扑;拓扑选择电路获取主电路变换后的输出,并将当前的输出值与参考值进行比较,根据两者的大小关系选择对应电压增益范围的变换拓扑。本发明的充电桩具备两种工作拓扑,具有较宽的电压范围。同时,在负载和输入变动的情况下选择不同拓扑结构满足负载需求,具有强适应性。
