AB  - In response to the growing demand for high power inverter unit, multilevel inverters have been attracting extensive attention from academia as well as industry in the recent decade. Among the best-known topologies are the H-bridge cascade inverter, the capacitor clamping inverter and the diode clamping inverter. In a three phase multilevel inverter, each phase of a cascaded multilevel inverter requires n DC sources to obtain 2n+1 output voltage levels. This study proposes a cascaded multilevel inverter with two unequal battery sources instead of three equal voltage battery sources for one phase to generate 7 level equal step output voltage waveform. This system can be used to drive a 3 phase Induction Motor of electric/hybrid electric vehicle, so that the cost and size of batteries can be reduced.
