| Abstract |
It is known that switching frequency greatly affects the variation in the difference in temperature between the junction and case, ∆TJC. In this paper the use of this effect when determining power cycling capability of IGBTs and free-wheeling diodes is investigated. This is achieved by modelling a typical inverter circuit. It is shown that IGBTs are stressed more than diodes for a typical load power factor. It is also shown that the switching frequency has a large effect on this stress. |
