Embodiment Construction

[0020] 1. Control system hardware structure:

[0021] The electric vehicle charger power supply is actually a switching power supply, which is composed of two parts: the power conversion main circuit and the control circuit. The system structure diagram is shown in the attachment figure 1 As shown, the whole system is composed of AC / DC converter module, DC / DC converter module, control system and other parts. The AC / DC converter module and the DC / DC converter module adopt multi-functional converter modules with the same topology. The main circuit of the multi-functional converter module is a three-phase full-bridge structure. Through software settings, the multi-functional modules can be composed of AC / DC, DC / DC converters. The multifunctional converter module includes two parts: IGBT (Insulated Gate Bipolar Transistor) module and digital controller. IGBT module is the main carrier of power conversion, mainly including IGBT main circuit, drive circuit, protection circuit, som...

Abstract

The invention provides a digital control system of a great-power bidirectional electric automobile charger system converter, belonging to the technical field of electric automobile chargers. The control system adopts a structure of matching a DSP (Digital Signal Processor) with a PLD (Programmable Logic Device) and combines the stronger data operational capability of the DSP, the high integration of the PLD and the repeated programming property of hardware, thereby making the structure of the controller hardware compact and greatly improving versatility, reliability and real-time property. The controller charger proposed by the invention can charge various batteries to reach a fully charged state at a higher speed without influencing the service life of the batteries and is convenient to adopt various intelligent charging strategies.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle chargers, and in particular relates to a bidirectional high-power charger power supply control system for electric vehicles using a digital signal processor. Background technique [0002] While automobiles bring convenience and comfort to human life, they also consume a large amount of oil resources, emit waste gas, and make noise, which also brings unavoidable negative effects on the natural ecological environment and human health. 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 ...
