This paper reviews the principles of three PWM control strategies, namely Harmonic Elimination, Current Hysteresis and Space Vector, which are used in the development of a 100kVA IGBT wind turbine inverter. Based on the simulations and the field test results, the comparison and selection issues of these PWM control strategies are investigated and addressed. The simulation and field test waveforms are reproduced.
