Abstract

The invention discloses an implementation method of an electric automobile direct-current charger control system based on an FPGA (Field Programmable Gate Array) and a Profibus (Process field bus). The charger control system consists of an AC / DC (Alternating Current / Direct Current) control module and a plurality of DC / DC (Direct Current / Direct Current) control modules, wherein both the AC / DC control module and the DC / DC control modules take the FPGA as an operation control core chip in order to realize signal sampling, pulse allocation and operation control functions; a communication framework based on a Profibus-DP (Process field bus-Decentralized Periphery) bus is adopted between the AC / DC control module and the DC / DC control modules. The AC / DC control module is taken as a main station, and the plurality of DC / DC control modules are taken as slave stations. The FPGA is taken as the core control chip, so that peripheral circuits of a hardware circuit are reduced, the interference resistance and reliability of the system are enhanced, the inter-module communication rate is increased, and the control timeliness of the system is ensured.

Description

technical field [0001] The invention belongs to the technical field of power electronics, relates to a control system of an electric vehicle charger, and is suitable for a general control component of a DC charger. Background technique [0002] With the deepening of the global energy crisis, the depletion of oil resources and the increasingly serious environmental pollution, governments of various countries and global automobile companies have realized that energy saving and emission reduction are the development direction of future automobiles. With the unanimous approval of manufacturers, people generally pay attention to and vigorously develop electric vehicle technology, and have achieved certain results and progress. [0003] As the equipment for charging the battery of electric vehicles, the electric vehicle charger is a power conversion device with specific functions. At present, electric vehicle chargers are divided into DC chargers and AC chargers. The charger is m...
