Example Embodiment

1. The overall structure of the two-way charger for electric vehicles:

The basic structure is shown in Figure 1. The power storage converter is composed of AC / DC converter modules, DC / DC converter modules, and control systems. Both AC / DC converter module and DC / DC converter module adopt the same multifunctional converter module. The main circuit of the multifunctional converter module is a three-phase full-bridge structure. Through software setting, the multifunctional module can form AC / DC, DC / DC converter. The multi-function converter module includes two parts: IGBT (InsulatedGateBipolarTransistor) module and digital controller. IGBT module is the main carrier of power conversion, mainly including IGBT main circuit, drive circuit, protection circuit, some sensors, buffer circuit, capacitance absorption circuit and other components. The universal digital controller is the main carrier of the control and communication functions of the multifunctional converter module. The AC...
