Abstract

The Direct AC to DC power converter is proposed for energy harvesting from low voltage supply. The conventional power converters uses diode bridge rectifiers and they are inefficient in operating at high switching frequency. The modified power converter avoids the use of bridge rectifier and directly converts ac input to the required dc output. The operation of the converter is based on Discontinuous conduction mode which increases the efficiency. The auxiliary circuit is added with the proposed converter to store the charges. The advantages of the converter are ripples are minimized, maintain the unity power factor and can effectively reduce the energy storage capacitance.
