How to estimate power losses in insulated-gate bipolar transistors?

Several techniques for estimating power losses in insulated-gate bipolar transistors (IGBTs), diodes and MOSFETs are known. Most of the approaches in the literature deal with PWM switching technique. In this paper presents a feasible loss model to estimate IGBT losses in a switching operation.

How to calculate power loss?

The first direct calculation can be used, involving RMS and AV values of voltage and current. By this method, all types of power losses can be estimated . Second, the indirect calculation of the losses using instantaneous values of the voltage and current can be used. .

What is a 5 level PWM inverter?

The developed five-level PWM inverter needs five controlled power switches and four isolated gate drive circuits. Furthermore, the proposed topology does not require bidirectional power semiconductor controlled switches, hence a conventional discrete power MOSFETs or IGBTs can be used to build the inverter circuits.
