摘　　要：根据大功率储能电池的充放电需求,介绍了一种适用于并网的新型充放电机。该充放电机采用AC/DC、DC/DC的双级结构,利用SVPWM技术完成了整流与逆变,在DC/DC变换侧采用了多重化的形式,在提高最大充放电功率的同时,极大地削减了直流纹波。经样机实验证明,设备输出交直流电流均得到较好的波形。In order to meet charging-discharging requirement of high-power battery, a new grid-connected deceive with an AC/DC and DC/DC dual-class structure was introduced. The device adopted SVPWM technology to complete the rectifier and inverter and the direct side adopted the DC/DC converter of interleaving type. It increased the maximum charge and discharge power, and at the same time, greatly reduced the DC ripple. Experiments show that the output of AC and DC current gets a better waveform.
