Novel space-vector-based harmonic elimination inverter control

摘要

This paper presents a novel space-vector-based pulsewidth modulation (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 techniques and does not require any of the intensive offline computations which are characteristic of optimized PWM strategies, thereby allowing a simple and efficient digital signal processor implementation.
