Abstract:   (1435 Views)
This paper proposes two new soft-switching transformerless converters with high voltage conversion ratio. These proposed converters achieve soft-switching each with a single auxiliary resonant cell. The merit of these converters is reduced switching losses with lesser number of devices. The main switching devices are turned off with zero current switching (ZCS). Apart from the soft-switching feature, the voltage conversion ratio is increased in comparison with the existing topologies. The operating principles and the simulation results on 12V/200V/500W converter system are presented in this paper.
 
Keywords: Conversion ratios, Transformerless converter(TLC), Zero voltage switching(ZVS), Zero current switching(ZCS), Voltage multiplier cell(VMC)
