摘要
由于当前V2G系统中普遍采用的电压型脉宽调制(pulse width modulation,PWM)整流方案中所存在的蓄电池电压匹配、功率体积比及系统效率问题,提出一种采用AC/DC矩阵变换器的解决方案。针对经典电流空间矢量调制策略中充电电流纹波较大的缺点,提出一种在全输出范围内减小充电电流纹波的分段优化调制策略,并深入对比分析这两种调制策略下充电电流纹波的大小。仿真和实验结果表明,所提分段优化调制策略的正确性和可行性。
The pulse width modulation (PWM) voltage source rectifier (VSR) for vehicle to grid (V2G) applications has some drawbacks due to its boost characteristic and multistage conversion. This paper presents a solution based on the AC/DC matrix converter topology for the V2G. Considering the characteristic of relatively large charging current ripple in the classical current space vector modulation strategy, a sectional optimized modulation strategy that can reduce the charging current ripple within the whole output range is proposed.
