aModeling And Simulation Of Bidirectional Converter For Solar Powered Refrigeration System

Refrigeration system is one of the essential utility nowadays, and the system needs to be made sustainable. Employing solar photovoltaic panel for refrigeration system is a reliable option. In this idea, the behavior of a PV run sun based chilling cycle is elementary. Sun based photovoltaic board develops dc electrical force that can make the dc engine work, which is linked to the blower of a fume pressure refrigeration framework. If a refrigeration system has to operate continuously a battery backup is required during the times of reduced PV output and using a bidirectional converter which will make the system sustainable. The bidirectional converter uses two voltage source converters (VSCs) which can act as a rectifier (VSC1) and inverter (VSC2) based on the percentual value of charge of the accumulator. The bidirectional converter charges the battery from supply mains whenever the battery SOC goes below a predefined threshold. The battery is supplied from a MPPT controlled DC/DC boost power modifier regulated PV output. If the battery reaches upper threshold of SOC the bidirectional converter works as an inverter taking supply from the DC/DC boost converter and give it to electrical network so a scheme have being modeled and simulated utilizing MATLAB R2014a and output is studied.
