Design and Implementation of space Vector Modulated Three Level Inverter with Quasi-Z-Source Network

Ranjutha.G, Kumaresan.R

A three level inverters with single quasi z-source neutral point clamped inverter using the space vector modulation technique is proposed in this paper. The proposed inverter has the main features in that the output voltage can be bucked or boosted and in-phase with the input voltage. The quasi z-source concept can be applied to all DC-AC, ACDC and DC-DC power conversion whether two-level or multi-level. Previous publications have shown the control of a Zsource neutral point clamped inverter using the space vector modulation technique. A three level inverters with single quasi Z-source is proposed in this project. This gives a number of benefits, both in terms of implementation and harmonic performance. The experiment results verified that the inverter has the lower input current harmonics distortion, a high efficiency, as it makes possible to avoid voltage spikes on the switches
