Novel space vector based harmonic elimination inverter control

摘要

This paper presents a novel Space Vector based PWM strategy which closely approximates in "real-time" the switching angles of the selective Harmonic Elimination PWM(HEPWM) strategy. The strategy uses only conventional Regular-Sampling techniquesand does not require any of the intensive off-line computations which are characteristic of optimised PWM strategies, thereby allowing a simple and efficient digital signal processor(DSP) implementation.
