Abstract
A comparison of pulse width modulation (PWM) strategies for three-phase
uninterruptible power supplies and motor drive systems based on the total harmonic distortion
of the current is presented. The well-known ‘exact’ PWM strategies of harmonic elimination,
harmonic minimisation, hysteresis band and space vector modulation are considered as a basis for
comparing the equivalent ‘regular sampled’ PWM techniques that have been developed to
approximate these exact strategies. Simulation and experimental results are presented to show the
differences between the various PWM strategies and to demonstrate the relative harmonic content
of each strategy.
