A novel harmonic elimination PWM strategy

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 for inverters. The strategy uses only conventional regular-sampled techniques and does not require any of the intensive offline computations that are usually associated with optimized PWM strategies, thereby allowing a simple and efficient digital signal processor (DSP) implementation.
