Abstract

This paper proposes a high performance “cycloconverter-type” high-frequency-link (HFL) single-phase rectifier with an active voltage clamper, which provides bidirectional two-stage galvanic isolation AC-DC power conversion. Modulation strategy, modeling method and control scheme are comprehensively developed for the HFL rectifier to guarantee its superior performances: a) two-stage power conversion and soft-switching switch devices lead to high conversion efficiency; b)complete elimination of voltage spikes during commutation ensures safe operation of high frequency switching devices; c)it can equally function as a high performance conventional PWM rectifier: sinusoidal input current, constant dc output voltage, bidirectional power flows between DC side and AC side, and adjustable power factor. A prototype of the proposed HFL rectifier is built for evaluation. The experiment results demonstrate the efficacy of the soft-switching HFL rectifier and its highly promising control performance. The proposed rectifier offers a high-efficiency, high-power-density, and high performance galvanic isolation power conversion solution to extensive applications.
