Abstract: This paper presents the modelling, simulation and implementation of solar photovoltaic cell using MATLAB Simulink. A high step up DC – DC converter is proposed. The conventional sources of energy are going to be exhausted in few years. The output voltage from most renewable sources like photovoltaic, fuel cell or energy storage device such as super capacitor and batteries are not useful for commercial usage. In order to make them to use we have to step up this voltage to grid voltage level so boost converter are introduced to meet the above mentioned requirement. The 15 V DC is step up to 230 V DC using high step up DC – DC converter. This DC is converted into AC by using inverter.
Keywords: Coupled inductor, DC–DC converter, high voltage gain, microsources.
