Tóm tắt
This paper presents a current controlled AC/DC converter for high frequency power architecture. The proposed converter employs a resonant network, a bi-direction shunt switch, an output transformer, synchronous rectifiers and an output filter. The resonant network is designed in such a way that it provides an AC current source at its output while drawing near sinusoidal input current. The operating principle of the circuit is given, and the steady state analysis is performed. It is shown that the converter has very high input power factor, low total harmonic distortion and fast transient response. Experimental and simulation results of a prototype converter converting the input AC voltage of 28 V RMS at 1 MHz, to 1.6 V DC at 20 A are given to verify the proof of concept, and analytical work reported in this paper.
