| 摘 要： | PWM整流器具有单位功率因数,谐波含量低,能量可逆传送等特点。介绍了单相全桥的高效整流器的电路拓扑结构和工作原理,针对单相电路直流侧二次纹波电压的特征,系统采用纹波电压补偿的方法;对于网侧电流的控制则采用了响应速度较高的定频滞环电流控制策略。给出了以TMS320F2407为控制芯片的系统硬件和软件实现过程,给出的实现思路对工程实际有一定的指导意义。

| Abstract: | The PWM rectifier with unity power factor, harmonic content of the low energy features such as reversible transmission was introduced. Detailed information of single-phase full-bridge rectifier circuit topology structure and working principle was analyzed. Due to the characteristic of second ripple voltage of single-phase circuit DC-side, the system compensated the ripple voltage. The fixed-frequency hysteresis current control strategy with higher response speed was used in net side current control of the s... |
