TRANSFORMERLESS DOUBLE BOOST CONVERTER FOR NON CONVENTIONAL ENERGY APPLICATION

Harshal D. Vaidya

Abstract: This paper presents a Transformer less Double Boost Converter (DBC) which delivers a feasible answer for non-conventional energy applications. The proposed DBC combines the conventional boost converter and the switched capacitor function. The tactic is to achieve double output voltage compared to conventional boost converter using appropriate duty cycle. The key benefits of this topology are: a continuous input current, a double conversion ratio without extreme duty cycle and without transformer, which permit high switching frequency. Simply single switch, single inductor, three diodes, three capacitors are desirable to design proposed DBC. The constituents present in the proposed converter are designed using performance equations. The proposed DBC converter is planned for rated power 100W, output voltage 100V with input supply voltage 20V. The proposed DBC is simulated in MATLAB and simulation result will authenticate the legitimacy of the theoretical design.
