Abstract
This study proposes a PV fed modified SEPIC converter controlled by P&O MPPT controller. The need of power converter in the field of Microgrid and renewable resource power generating system is indispensable. Particularly the usage of Transformerless converters is kept increasing and the advancement of power electronics lead to modifications in power converters. Such action results in designing of compact sized converters with fewer components to obtain high output power. In accordance with that, this study proposes a modified SEPIC converter to tackle any change in input or load demand. Furthermore, the simplest P&O MPPT controller aids in regulating the operation of converter to balance the load demand. The analysis of this proposed study is carried out by adjusting the irradiance of solar panel at constant temperature to analyse the effectiveness of the converter. This proposed converter reached maximum voltage and current gain of 597.3V and 18.7A, respectively. Hence, the results proven that this converter performed better than several other converters.
Keywords: PV Module, Modified SEPIC Converter, P&O MPPT Controller, Transformerless Converter, Duty Ratio.
