Abstract

We introduce 2[MVA] 3300[V] 7-level voltage source inverter system developed by POSCON and describe the main characteristics of inverter system i.e. PWM converter, H-bridge power module, phase shifted carrier PWM The PWM converter is a three-phase boost converter, which operates in a 4-quadrant and in a nearly unit displacement power factor. Experimental waveforms are also presented to verify the proposed method and performance of the developed system.
