A Half Bridge Inverter with Ultra Fast IGBT Module-Modelling and Experimentation
This paper presents an operation analysis of the single-phase half bridge inverter with the ultra fast IGBTs (Insulated Gate Bipolar Transistors) and with freewheeling diodes (module SKM100GB125DN, manufactured by Semikron). Simplorer software package, which is especially suitable for electrothermal modelling of power electronics circuits, is used for the inverter operation modelling. In addition, a laboratory setup of the inverter is built in order to experimentally verify simulation results. The control unit of the inverter consists of a stabilized power supply, SG3525A pulse-width modulator and SKHI22B hybrid dual driver. At the same time, the ability to change the transistor switching frequency and dead time is provided. Good agreement of simulation and experimental results is confirmed.
