This paper presents function of a solitary switch high advanced dc-dc converter based on quadratic boost. The proposed converter has the simple structure low cost and ease of control. quadratic boost and switched capacitor is used as primary and secondary circuit, here for the connection coupled inductor is applied between them, so the converter achieves high step up voltage gain with appropriate duty cycle and reduction of voltage stress on the power switch moreover the energy stored in leakage inductance of coupled inductor is recycled to the output and stress on the input source is reduced, so input current of the converter is continuous. The main aim of this converter is to obtain at the same time high conversion ratio and excelling efficiency for a wide source voltage range. The dc voltage conversion ratio of these converters have a quadratic dependence on duty cycle Providing large step up and offering the possibility of higher switching frequency. Solitary switch Quadratic boost converter is presented and assessed using MATLAB/Simulink (MLS) with the SimPowerSystem block set and the results of simulations are presented to evaluate the behaviour and feasibility of the proposed topology. The circuit is reproduced with 24v information voltage for a yield voltage of 400v. The activity of the proposed framework has been discovered attractive.
