大功率逆变器混合脉宽调制策略研究
Research on multi-mode pulse width modulation strategy for high-power voltage source inverter
摘要
Abstract
When the high voltage and high current switching devices are applied to high-power traction system, the switching frequency is very low. In view of the deficiencies of the current overmodulation method and the intermediate 60°SPWM control, this paper proposes a multi-mode pulse modulation strategy which uses the Selective Harmonic Elimination Modulation for the intermediate frequency, and realizes the smooth transition between Asynchronous SVPWM, Synchronous SVPWM, SHEP-WM and the square modulation. The results of simulation and experiment indicate that the inverter has good output characteristics in the entire modulation range.关键词
