摘要:
为解决电动汽车充电桩充电效率低的问题,以契合高功率因数运行,提高充电效率为应用背景,提出了一种新型拓扑结构的直流充电桩,该结构由三相电压型PWM 整流器和半桥LLC 谐振变换器组成。运用双闭环控制方法及空间矢量脉宽调制技术作为控制策略,得出其在不同坐标系下的数学模型及外特性。基于Matlab/ Simulink 平台,搭建了一台100 kW/500 V 输出的实验样机,仿真结果表明:在双闭环及空间矢量脉宽调制的控制策略下,该新型结构可实现高功率因数运行、输出电压稳定的功能,验证了该结构可提高充电效率的优势。
Abstract:
To solve the problem of low charging efficiency of electric vehicle charging piles, a new topology of DC charging pile was proposed against the application background of high-power factor operation and charging efficiency improvement. The structure consists of a three-phase voltage source PWM rectifier and a half-bridge LLC resonant converter. With the dual closed-loop control method and space vector pulse width modulation technology as the control strategy, its mathematical model and external 〖JP2〗characteristics in different coordinate systems were obtained. Based on the Matlab/Simulink platform, an experimental prototype with 100 kW/500 V output was built. Simulation results show that under the control strategy of dual closed-loop and space vector pulse width modulation, this new structure can realize high-power factor operation and stable output voltage, verifying the advantages of this structure in improving charging efficiency.
