摘要

采用恒频峰值电流模式编程代替传统的低带宽电压模式编程控制，实现了在断续导通模式下工作的单位功率因数自动电流形成器的控制方案。其主要优点是可以获得极低谐波失真(THD<1.5%)的输入电流。指出了控制系统潜在的稳定性问题，并提出了一个简洁的解决方案。

Low-distortion control of unity-power-factor converters in discontinuous conduction mode

A control scheme for unity power factor automatic current shapers operating in discontinuous conduction mode uses constant-frequency peak current mode programming instead of the conventional low-bandwidth voltage mode programming control. The main advantage is that an input current with very low harmonic distortion (THD<1.5%) can be obtained. A potential stability problem of the control is identified and an elegant solution suggested.
