工业自动化技术迅猛发展，变频器技术也日益趋于完善。目前，变频器广泛应用于各个行业领域中，随着变频器功能不断强大，可靠性也不断在提高。如果变频器在使用不当，操作有误，维护不及时，仍会发生故障或停运状况，以致缩短设备的使用寿命。那常见的变频器故障有哪些呢？
一、变频器充电电路故障
起动电阻被烧坏，变频器报警显示为直流母线电压故障这些都是属于充电电路故障。当变频器的交流输入电源频繁通断时，或者短路接触器的触点接触不良或晶闸管的导通阻值变大时，都会导致起动电阻被烧坏如果是遇这种状况，可购买同规格的电阻更换。这是需要找出烧坏电阻的原因，如果故障是由短路接触器触点或短路晶闸管引起，则必须更换这些元器件，才能再将变频器投入使用。如果故障是由输入电源频繁通断引起的，必须消除这种现象。
二、变频器整流模块损坏
变频器的常见故障就是变频器整流模块的损坏，如今大部分整流模块则采用晶闸管代替早期二极管。由于整流器件易过热，易被击穿，当其损坏后伴随着快速熔断器熔断，导致整机停机。在替换整流模块时，要求其在与散热片触摸的面上均匀地涂上一层传热功能杰出的硅脂，再紧固装置螺丝。若是没有同类型整流模块时，可用同容量的其他类型的整流模块替代。整流模块的损坏常与机器外部电源有密切关系，当整流模块发作毛病后，不能再盲目上电，应先查看外围设备。
