摘要
功率因数校正(power factor correction,PFC)被广泛应用于车载充电机以提高充电效率、减小对电网产生的谐波污染.本文常用的双闭环比例积分(proportional integration,PI)控制的基础上,研究了退火粒子群算法(particle swarm optimization,PSO-PI)和改进重复比例谐振(proportional resonance,PR)控制,通过退火PSO算法对电压环的PI控制器参数进行优化,提高了响应速度;将电流环由PI控制变为改进重复PR控制,以解决PI控制对高频信号跟踪能力弱的缺点,并选用了近几年比较热门的图腾柱PFC拓扑结构,最终提高了响应速度,降低总谐波畸变率(total harmonic distortion rate,THD).最后通过Matlab/Simulink仿真验证了控制策略的正确性,相比传统的图腾柱PFC,响应速度得到一定提高,THD值降低了2.07%.
Abstract
PFC(power factor correction)is widely used in on-board chargers to improve charging efficiency and re-duce harmonic pollution to the grid.Based on the commonly used double closed-loop PI(proportional integration)control,studied annealed PSO-PI(particle swarm optimization)and improved repetitive PR(proportional reso-nance)control,and the PI controller parameters of the voltage loop are optimized by annealing PSO algorithm to im-prove the response speed.The current loop was changed from PI control to improved repetitive PR control to solve the shortcomings of PI control with weak tracking ability of high-frequency signals,and the popular totem pole PFC topolo-gy in recent years was selected,which finally improved the response speed and reduced the THD(total harmonic dis-tortion rate).Finally,the correctness of the control strategy is verified by Matlab/Simulink simulation,and compared with the PI-controlled totem pole PFC,the response speed is improved,and the THD value is reduced by 2.07%.
