摘要
以传统通用变频器的不足作为研究方向和目标,首先对PWM整流器的电流控制策略和逆变器的控制分别进行了研究,然后在此基础上提出了基于功率直接反馈的双PWM变频器的一体化控制方法,并给出了仿真结果和分析,仿真结果表明,系统达到了预期的控制目标。
The insufficient of the traditional universal inverter is taken as the research direction and goal,the current control strategy of the PWM rectifier and the control of the inverter are first researched, and then a control method for the double PWM frequency converter based on the direct power feedback is studied. The simulation results show that the control method can be realized and the system has a nice dynamic and static performance.
