摘要
阐述了PWM变频调速的基本原理,分析了传统隔离方案的变频调速控制器的典型拓扑,给出了采用共地方案实现的变频调速控制器原理,并对其硬件设计进行了详细的分析。实验结果表明:采用共地方案可以达到简化硬件电路的设计,有效降低硬件成本,并能够获得较好的控制效果,文中最后给出了不同频率下的实验波形。
The principles of VVVF inverter is described in detail, and typical topology of inverter is also analyzed. The scheme and the design of inverter with one ground are also discussed. The hardware circuit becomes simple, and the cost becomes lower when this scheme is applied. Finally, some experiment results are given.
