摘　　要：随着VVVF逆变器在工业生产中的广泛应用，逆变器的维修工作变得越来越重要。但是，逆变器维修工作是十分困难的，其重要的原因之一是用户对逆变器的内部结构了解甚少。本文介绍了日本富士公司生产的FRN110G7－4EX型变频器的部分线路结构及其原理，以便为设计和维修变频器提供依据和参考。Along with the widespread application of variable voltage variable frequency (VVVF ) inverters in industry production, the maintenace of inverter becomes more and more importan. But it is an extremely difficult problem to maintain the inverter, the main cause is that the user would not know the intemal hardware structure of the inverter. This paper introduces the results of study and analysis on the internal hardware Structure and principle of FRN110G7-4EX inverter to provide guide and reference for designingand maintaining inverter.
