电动汽车充电模块并联控制策略研究

Research on Parallel Control Strategy of EV Charging Module

随着传统能源的不断消耗以及可持续发展战略的不断落实,我国开始越发重视新能源汽车的生产和销售.而新能源汽车市场结构中电动汽车占据了90%,因此做好电动汽车充电模块的研究至关重要.基于此,文章首先从零序环流模型和零序环流的抑制方法对三相整流器并联控制策略进行研究,其次给出一种基于一致性算法的均流控制策略,最后利用Matlab/Simulink仿真软件对零序环流进行仿真,从而验证零序环流抑制方法和均流控制策略的有效性.

With the continuous consumption of traditional energy and the continuous implementation of the sustainable development strategy,China began to pay more and more attention to the production and sales of new energy vehicles.In the market structure of new energy vehicles,electric vehicles account for 90%,so it is very important to study the charging module of electric vehicles.Based on this,this paper fi rst studies the parallel control strategy of three-phase rectifi er from the zero sequence circulation model and the suppression method of zero sequence circulation,then presents a current sharing control strategy based on the consistency algorithm,and finally uses Matlab/Simulink simulation software to simulate the zero sequence circulation,so as to verify the effectiveness of the zero sequence circulation suppression method and the current sharing control strategy.
