In this paper a simple algorithm of space vector pulse width modulation (SVM) for two-level voltage-fed inverter is proposed. The idea of algorithm is that a single algorithm covers the undermodulation and overmodulation range including six-step mode. The algorithm unifies equations to determine angle of reference voltage vector Uc in undermodulation and overmodulation mode I, therefore simplifies calculation program. The open loop control of the induction motor, a smooth operation during transition from the linear control to the six-step mode is demonstrated through experimental results using Matlab/Simulink simulation.
