Abstract :
This paper presents a feasible loss model to estimate IGBT losses in a soft switching operation. The loss model is developed based on the experimental determination of the power losses. This paper investigates the power losses in IGBT´s as a function of the circuit and its operation parameters, in order to help the device selection for a given application. In addition, it compares the losses produced by hard-switched and quasisquare-wave inverters for different currents. The study takes into account conduction losses, switching losses (turn-on and turn-off losses) and losses in the passive components.
