Abstract

Abstract

Based on the AC-Link^TM energy conversion method, this paper improves the topology and working mode of the converter, so that the resonant circuit can work in bipolar mode, and designs the corresponding commutation timing and control algorithm based on the new topology, which enhances the adaptability of the converter to the three-phase input voltage fluctuation, so that it has the theoretical boost capability and high input power factor. Using Matlab/Simulink, a 30 kW simulation model was built, and the simulation results show that the output voltage reached 3kV and the boost capacity reached 6 times under the conditions of three-phase grid input, transformer ratio 1∶1 and resistive load, indicating that the converter has the ability to operate over a wide range of output voltages
