Design and Implementation of a Novel Transformer less DC to DC Converter for LED Display Application

This paper uses high frequency transformer less chopper with voltage boosting and low stress. The topology uses automatic current sharing capability and voltage summing at the output terminal by lower value of MOSFET, diodes. In addition to this proposed technology losses are reduced. Blocking capacitor introduces automatic current sharing in the circuit because of charge balance in the capacitor. The proposed topology provides voltage boosting with no extreme duty cycle. In relating to the existing proposed system voltage gain is proposed. Electrolytic capacitor used to reduce the current ripple .By having more current ripple will reduce the output port power in the circuit .Incase if output diode stress greater than the output voltage efficiency of circuit reduces for high output voltage application. The reduction of voltage stress and voltage gain can be achieved using ultra high step-up convertor with addition to power factor correction by voltage doubler circuit.
