MPPT-current fed push pull converter for DC bus source on solar home application

This paper presents the design of MPPT-current fed push-pull converter. Because of the high step-up transformer ratio and the transformer works at high frequencies, the converter is suitable for low voltage photovoltaic applications. Photovoltaic is a renewable energy that has several advantages, i.e., no pollution (no emissions), no noise, little maintenance and an abundant resource. The photovoltaic used in this study was 300Wp with a DC Bus of 400V. To optimize the working of photovoltaic used MPPT technique. The MPPT technique chosen is Perturbation and Observe. In the proposed converter, an inductor installed on the input side serves as a voltage boost so that the transformer ratio is not too high.
