摘要
在空调压缩机测试平台中,对测试电源的输出电压波形要求较高,频率、电压的可调节范围要求较广。采用PLC控制的旋转式变频电源系统很好的满足了以上要求,实现了输出电压频率和幅值的连续可调,在实际应用中取得了良好的效果。
In the testing bedding an air condition compressors, the output of thd power supply is expected to be ideal wave adjustable in frequency and voting range extensively .The paper introduces a revolving frequency-cycle type power supply, which is based on PLC, adapted to the requirements listed above and realizing continually in frequency and voltage. The revolving frequency-converting power supply in practical use.
