摘要:
峰值电流控制是Boost PFC(升压功率因数校正)变换器常用的一种控制方式,但大多用于电流连续模式(CCM)。电流断续模式(DCM)使用正弦峰值拟合曲线时,存在电流的平均值曲线不能为正弦、功率因数(PF)较低问题。为此,文章通过推算DCM模式下的电流特性,修正了峰值拟合曲线;使用该峰值曲线进行控制,不仅可提高功率因数,而且在一定程度上构成了对电感电流的闭环控制,提高了电路的可靠性。PSIM仿真和样机实验结果证明了该方法的有效性。
Abstract:
Peak current control is widely used in Boost power factor correction( PFC) converter, but mainly used in continuous conduction mode (CCM). Since the sinusoidal peak fitting curve is used in the discontinuous conduction mode (DCM), the average curve of a current cannot be sinusoidal and the power factor (PF) is low. In this paper, based on the calculated current characteristics in the DCM mode, a peak fitting curve was derived, and it can be used to improve the power factor. Moreover, to a certain extent, it constitutes a closed-loop control of the inductor current, which improves the reliability of the circuit. By PSIM software simulation and prototype experiment, the control method was proved to be effective.
