中小功率变频器输入输出反接故障的分析

Analysis of Inversed Fault for Medium and Low Power Frequency Converter Input-output

分析了中小功率变频器正常运行时和输入、输出接反时电路的工作特点,得到如何在输入、输出接反是故障时,找出可能损坏的元器件,以便工程技术人员快速地排除故障。

The operation characteristics are analyzed when the medium and low power frequency converter is in normal operation and the input and output are inversed with the circuits. Get to know how to find out possible damaged parts they are faults when the inpuct and output are inversed. Thus engineers and techniciaus can quickly remove the faults.
