ADVANCED CONTROL OF PV-BATTERY INTEGRATED SYSTEMS FOR HIGH VOLTAGE RIDE-THROUGH AND POWER ROUTING APPLICATIONS

Abstract

This research describes a new configuration for the step-up DC-DC converter. Distributed generation (DG) components such as solar PV arrays, micro-turbines fuel cells, and ultracapacitors are part of a DC micro -grid; the output voltage in DC micro-grids heavily relies on the DC-DC converter. Increasing the output voltage of a DC-DC converter is required due to the low output voltage of DG sources. Since the voltage stress would be a significant drawback of conventional boost converters, this suggested configuration was designed with quadratic voltage gain and lower voltage stress which reduced the voltage stress across the switch. Structure we compared our configuration with the different designs like positive super lift Luo throughout the paper. The validation of theoretical findings demonstrates simulation and experimental results KEYWORDS— new step-up boost converter, quadratic boost converter (QBC), Solar system, high DC gain ratio.
