Single-phase Switching Pattern optimized SVPWM Technique

为了有效降低单相逆变电源的开关损耗,提出将三相开关模式优化空间矢量脉宽调制(SVPWM)技术思想应用于单相 PWM逆变电源,并阐述了该技术的实现方法。理论表明,单相优化 SVPWM技术与传统单相双极正弦脉宽调制(SPWM)技术相比,可降低50%开关损耗。实验验证了该技术的有效性。

For reducing the single-phase PWM inverter switching depletion,the 3-phase switching pattern optimized SVPWM technique is applied to single-phase PWM inverter.And the realization method is described in detail.Compared with the traditional single-phase dipolar SPWM technique,the single-phase switching pattern optimized SVPWM technique can reduce 50% inverter switching depletion in theory.The experiment is taken to prove those theory.
