Transient Response Analysis of PV based Non- Isolated Two Phase Interleaved Boost Converter for Standalone DC Microgird

Abstract

The electrification of villages depends heavily on renewable energy sources. Village electrification works best with PV fed independent micro grids be-cause grid connected micro grids require infrastructure expansion and take about a year to reach the settlements. This study focuses on developing a Two Phase Non – Isolated Interleaved Boost Converter (TPNI-IBC) with a voltage improving module, which serves as a suitable intermediate candidate for coupling a photovoltaic green source to a DC load. Because PV is spo-radic in nature and generates small voltage, the suggested converter is con-structed to offer substantial voltage improvement with a low duty cycle. The converter under consideration is constructed to reduce the voltage stress on the switches and diodes.In turn-off operation, the clamp circuit lessens volt-age spikes of the power devices and recycles the energy of the linked induc-tor's outflow. Additionally, PID controllers and fuzzy logic (FL) controllers are employed to stream controlled DC bus voltage at various photovoltaic ar-ray irradiance levels. The controller and FLC both produce better outcomes when the transient response parameters such as settling time and peak over-shoot are compared.
