三电平SVPWM与双调制波载波PWM的等效研究
Research of the equivalence between three-level SVPWM and double modulation wave carrier-based PWM
摘要
Abstract
The three-level SVPWM has the advantages of high utilization rate of direct pressure, low THD, while its realization is complicated. According to the problem that single modulation wave carrier-based pulse width modulation isn't equal to space vector pulse width modulation when the switching sequence is more than 8 segments, this paper introduces a method of double modulation wave carrier-based pulse width modulation to solve it. The equivalence be-tween three-level space vector pulse width modulation and double modulation wave carrier-based pulse width modula-tion was thoroughly studied in this paper . The relationship between the 6 sub-modulation waves and the three-phase o-riginal modulation wave, DC voltage is obtained when the reference vector is located in different areas of different sec-tors. The experiment result verifies the correctness of the proposed method.关键词
