This paper proposes a simple space vector PWM algorithm for a multilevel inverter, which (a) can cover sinusoidal and overmodulation mode (b) can easily determine the location of reference vector and calculate the on-times. The proposed scheme is explained for a 3-level neutral point clamped inverter with operation in sinusoidal and overmodulation modes. The scheme can be easily extended to any level of inverter. Experimental results are provided
