采用電感電壓控制的新型Buck AC-DC 變換器

摘要：介紹了一種用于Buck AC/DC 變換器的新的控制方法(IVC)，該方法可用于任意功率因數調節的電路。仿真和實驗有力地證實了該控制方法不易受參數變化或控制信號變化的影響。 敘詞：電感電壓控制 交直變換器 單位功率因數 Abstract：A novel inductor voltage control(IVC) method capable of achieving any input power factor including unity is being proposed for buck-type ac-dc pulsewidth modulation(PWM) converters. Simulation and experiment verify this control is much less sensitive to parameter and control signal changes than the existing delta modulation control.
