Abstract
A novel switching loss reduction technique for three-phase PWM rectifier-inverter topology (Fig. 2) for UPS applications is proposed in this paper. This hybrid topology uses only nine IGBT devices for AC/AC conversion through a quasi d.c. link circuit. this novel switching loss reduction technique will reduce the switching losses and improves the total harmonic distortion of the nine switch inverter. The operating principle of the converter is elaborated and a dedicated advanced space vector modulation scheme is presented. The performance of the proposed converter is verified by simulation on a 5 kVA prototyping UPS system.
