#189067 - IGBTs and money
Responding to: Mahmood Elnasser's previous message
When I worked extensively with Inverters I learned that 400V inverters with 1200V IGBTs blew the IGBTs occasionally whereas 1400V IGBTs did not. All calculations show that 1200 is enough. So DO NOT save money by using an IGBT that is "just enough"
