A power quality enhancement system using a one stage AC to DC non wired power transfer converter.

Wireless power transfer technology is being emerging and is used in various applications. These combine the usage of rectifier conversion from ac to dc, the various required levels of dc-to-dc conversion obtained using a single stage conversion. The power is fed from three phase supply with a 50 Hz frequency for higher level applications. In this paper a resonant converter is utilized to obtain a one stage conversion from a three-phase supply. To improve the efficiency and to enhance the quality of power with correcting power factor to required level by controlling the voltage level in the bus is proposed in this paper thereby reducing the expenditure and complication for increased power wireless power transfer scheme. The power quality enhancement using power factor improvement and dc to dc conversion without wired power transmit features is obtained using a T-type topology as the three-stage converter. A one stage conversion is proposed by reducing the number of semiconductor switches, and hence economic when comparing with other multistage techniques with wireless power transfer technology.
