Protect IGBTs by Sensing Current Using Optical Isolation Amplifi ers
May 16, 2012 // Hong Lei Chen, Avago Technologies // 0 commentsDownload White Paper 151Ko
Insulated-gate bipolar transistors (IGBTs) require full protection to avoid damage and failures resulting from conditions such as short circuits, overloads and overvoltages. The protection is key to ensuring safe and stable power-converter operations in applications such as motor drives and solar and wind power generation systems. To detect over-current and overload conditions, isolation amplifiers featuring fast response or fast fault feedback can be used on the output phases and the DC bus.
