【摘要】：针对光伏发电系统在电动汽车充电应用中存在充电时间长、充电电压波动大及最大功率点跟踪(MPPT)速度慢等问题,研究并设计一种车载环境下太阳能充电系统。基于电导增量法,提出适合车载工况下的修正变步长电导增量MPPT法。对充电系统中实现MPPT控制的Boost电路,与用于充电控制的Buck电路以及PI控制器进行建模与分析。基于PSIM仿真平台验证所提MPPT法的快速追踪性能,及充电系统充电电压摄动小、稳态精度高;又通过有无MPPT功能的充电实验对比,表明系统还具有充电时间短、效率高的优势。
[Abstract]:Aiming at the problems of long charging time, high voltage fluctuation and low speed of MPPTs in the application of photovoltaic power generation system in electric vehicle, a solar charging system in vehicle environment is studied and designed. Based on the conductance increment method, a modified variable step increment MPPT method is proposed for vehicle operation. The Boost circuit which realizes MPPT control in charging system and the Buck circuit and Pi controller used for charging control are modeled and analyzed. Based on the PSIM simulation platform, the fast tracking performance of the proposed MPPT method is verified, and the charging system has the advantages of low voltage perturbation and high steady-state accuracy, and through the comparison of charging experiments with or without the MPPT function, it shows that the system also has the advantages of short charging time and high efficiency.
