Transformerless Large gain Boost Converter with Input Current Ripple Cancellation for a given Duty Cycle

ABSTRACT This paper proposes a boost dc-dc converter without transformer gives the novel capability of cancelling the input current ripple with high gain output voltage at preselected duty cycle. There are several solutions available in literature to get the high gain voltage but they use number of components, But in this proposed system without increasing the number of components, the converter features a high voltage gain without utilizing boosting transformers the main purpose of proposing this system is to make best use of electric power coming from low voltage power generating sources such as renewable. Finally a prototype circuit of the proposed converter is implemented in laboratory to verify the performance of the converter.
