The turn-off losses are estimated in the case of CIC NPT IGBTs operating on inductive load for snubberless turn-off operations. Only technological or electrical informations are needed, that are available from data sheets. In order to estimate the losses, IGBT's behaviour in the conduction state and in the voltage reapplication phase is described with the help of a one-dimensional analytical model. The stored charge removal is modelled in an elementary way to calculate the turn-off losses as a function of load current, of supply voltage and of case temperature. The calculated values of turn-off losses are compared with experimental results and also with results obtained in a bi-dimensional numerical simulation.
