摘要
分析了变频器实现异步电动机回馈制动的原理 ,提出了一种新颖的能量回馈控制策略和泵升电压抑制电路 ,并从能量转换的角度出发 ,对两种能量控制方式的泵升电压抑制电路进行了研究 。
The brake principle of the asynchronous motor supplied by the inverter is analyzed in this paper. A novel measure of energy regenerative control and a pump voltage circuit are proposed.The pump voltage circuits of the two kinds of energy control are researched from the energy conversion and the real parameters of circuits are given.
