摘　　要：为适应储能电池的应用场合,设计了一种适用于并网的新型充放电机。采用AC/DC,DC/DC的两级结构,采用空间矢量脉宽调制(SVPWM)技术实现逆变与整流,在DC/DC变换侧采用二重化形式,在提高最大充放电功率的同时,有效抑制了直流纹波。实验结果表明装置在直流侧与交流侧均得到较为理想的波形。In order to meet charging-discharging using needs of storage battery, this paper introduces a new grid-connected device that uses a AC/DC and DC/DC dual-class structure.Space vector pulse width modulation（SVPWM） technology is introduced into the device to complete the rectifier and inverter.The direct side using the DC/DC converter of interleaving type.It increases the maximum charge and discharge power and greatly reduces the DC ripple.Experimental results show that the output of AC and DC current get a better waveform.
