【摘要】 详细分析和推导了电压源逆变器传统的三角载波电流控制PWM方法,指出其具有无法克服固有跟踪误差的缺点,以及可使功率开关器件开关频率固定的优点。提出了改进方法,该方法具有很强的跟踪能力,可供大功率逆变器及有源滤波器等设计作参考。更多还原

【Abstract】 The conventional triangular carrier current control PWM strategy for single-phase voltage inverters is analyzed and deducted in detail. A modified model is presented, which has strong traceability and can be a reference for the design of power inverters and APFs.更多还原
