| 摘 要： | 本文提出了一种新颖的交直调速方案。该方案把原交直交电流型变频器的主电路简化了一半,省去了变频器中把直流电再逆变成交流电的环节,故是一种交直调速方案。本文提出的方案不仅佐证了交直调速的可行性,而且由于提出了新的实现方法,具有实践意义。

| Abstract: | A method of regulating AC motor's speed by changing the frequency of current VVVF has been put in to practice. But, a VVVF speed regulator is very complicated and costly. Therefore, how to simplify the speed regulator is a problem to be solved urgently. In this paper, a circuit has been put forward, which is a new ac-dc type of speed regulation circuit. It has only three SCR in main bridge, so the circuit is very simple and the cost is low. |
