Abstract
Boost converters operated in critical mode can achieve high efficiency, while they have some limitations, such as high current ripple, high component rating and low power application. Thus, this paper proposes integrated circuits (IC) of a powerfactor corrector (PFC) controller for interleaved critical-mode boost converters. The proposed PFC control IC can achieve the features of interleaving function, zero voltage switching, wide input voltage range and wide output load range. Simulated results obtained from two-phase boost converters with the proposed PFC IC have verified the features and control schemes of the proposed controller.
