In this paper, the authors bring out the observation that the space vector representation of four switches three phase inverter. It is used to develop a simple and generalized Space Vector Pulse Width Modulation (SVPWM) algorithm for two legged multilevel inverters. The space vectors of any n-level inverter can be generated from the vectors of 2-level inverter using simple addition operation and doesn't use any look up tables. The simple addition operation used for the generation of space vectors of n-level inverter is also used to generate the inverter switching states of the corresponding vectors.
