| Abstract: | Based on the traditional space vector pulse width modulation (SVPWM), this paper presents a hybrid space vector pulse width modulation (HSVPWM) through changing the position and sequence of the zero vector. This paper also introduces the way to realize the HSVPWM by digital signal processor (DSP) TMS320F240, and gives the experiment result comparison with the traditional space vector pulse width modulation. Theoretical analysis and practical application show this improved HSVPWM can reduce the switching frequency of applied power device by a factor of 1/3 and can restrain the current oscillation efficiently. |
