摘　　要：对客车逆变电源输出并联系统进行了研究,阐述了逆变电源输出并联运行时的相位和幅值差与逆变器输出的有功功率与无功功率的关系,提出一种通过对逆变器各自输出的有功功率和无功功率进行实时检测和计算、调整各逆变器输出电压的幅值和频率以达到多台逆变电源无线并联运行的方案。实验结果表明,该系统运行稳定,设计方案有效。It studied vehicle inverter-parallel power supply system, described the relationship between phase and amplitude error of the system output and active power and reactive output power of the inverter. A scheme of wireless multiple-inverter-parallel operation was presented which adjusted the amplitude and frequency of output voltage through real-time detection and calculation of respective output active power and reactive power of inverters. Experimental results show that the system operates steadily and the validity of this design is verified.
