Abstract |
A new topology of single-phase two stage AC to DC SEPIC converter in step down configuration with high efficiency at extremely low voltage gain is proposed with high input power factor and low input current total harmonic distortion. In this work, proposal has be given to modify conventional two stage AC to DC SEPIC converter introducing a switched capacitor branch in between the stages. The input current THD is kept low. The input power factor is high with two-loop feedback control. The proposed schemes can be used in the application of battery charging of electric motor vehicles. |
