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...

Abstract

The invention relates to a main circuit topology structure of an electric automobile bidirectional charger converter based on a power electronic module, which comprises a bidirectional four-quadrant AC/DC converter module, a bidirectional DC/DC converter module and a control system. The control system comprises two identical general controllers for respectively controlling the converter process of the AC/DC converter module and the DC/DC converter module. The invention enables the converter to have compact hardware structure and greatly improved universality, reliability and modularity degree.

Description

Electric Vehicle Bidirectional Charger Power Supply Topology technical field The invention relates to a power supply topology structure of a bidirectional charger for a high-power electric vehicle, in particular to a main circuit structure of a bidirectional high-power charger for an electric vehicle using a modular converter. Background technique At present, as countries around the world pay more and more attention to vehicle emission control and energy issues, clean, environmentally friendly and energy-saving electric vehicles have become a hot spot in the development of the world's automobile industry. According to my country's national conditions, the development of electric vehicles is imminent. Electric vehicles, as the name suggests, are vehicles that use batteries as all or part of their power source. At present, there are two main aspects that restrict the development of the electric vehicle industry: one is the battery itself, and the other is the charging metho...
