摘要: In this paper, a new three-level single-stage power-factor-corrected ac/dc converter is presented. The proposed circuit integrates the operation of boost power factor correction and dc/dc into one converter. It does not have problem high component stress due to rising intermediate bus voltages at light load conditions that other converters because its structure. can operate over wider range with significantly less output inductor current ripple; moreover, input has little distortion. explained in detail analyzed, steady-state characteristics are determined, design discussed. Experimental results obtained from prototype presented confirm feasibility
