Abstract

The paper presents a modular multi-cell three-level five-phase voltage source inverter. The topology is an extension of a single-phase H-bridge inverter. Positive and negative voltage levels are obtained by operating two switches at one time while zero voltage level is obtained by shorting the load side. The source side shorting is avoided in order to protect the source. The major advantage is multi-level output without capacitor voltage or neutral voltage balancing in contrast to the more commonly used neutral point clamped type and flying capacitor type. The major disadvantage from the industrial application point of view is the requirement of five isolated dc sources. Mathematical model is derived and presented. Modulation is obtained using simple phase disposition and level shifted sinusoidal carrier based scheme. A five-phase induction machine is considered as load and excitation and loading transient is presented. The simulation model considered the effect of dead-band in the switching signals. Further the effect of change in DC link voltages of different cells are also investigated and reported. The simulation and experimental results are shown.
