一种CCM Boost PFC变换器的离散占空比控制：原理、建模与分析

In this article, a discrete duty ratio (DDR) control strategy is proposed to improve both power factor (PF) and transient response performance for boost power factor correction (PFC) converters operating in continuous conduction mode. By directly generating discrete duty cycles to fit a target duty ratio with unity PF and reference output voltage, the proposed control can achieve fast, accurate, a...
