摘要
本文提出了一种由单片机（８０９８或８０Ｃ１９６）作ＣＰＵ的变频控制器的故障诊断方法，介绍了该方法的硬件电路和软件设计，这种方法可以有效地防止变频器的“倒灌”问题。
This paper presents an accident prevention method of inverter controller which uses a single chip microcomputer (8098 or 80C196) as the CPU and introduces its hardware circuit and softwsre design. The method can effectively solve the 'flowing backward' problem of inverters.
