Abstract

A novel algorithm for space vector pulse width modulation in three phase power factor correction applications is proposed. The durations for the active vectors that formed the sector containing the desired reference voltage vector are calculated directly by matrix pre-decomposing, without looking up sinusoidal and tangential tables, based on TMS320F240. Therefore running speed and control precise of the program can be improved greatly. As a result the switching frequency and power density of the rectifier is increased considerably. A new method for detecting sector is given as well. Simulated and experimental results are provided to verify the proposed algorithm in the end of the paper.
