SOLAR ENERGY BASED LAPTOP CHARGER USING QUADRATIC BOOST CONVERTER

Abstract

            A quadratic boost converter is designed to get the Laptop charger rating 63.5W in this research. This converter is energized with solar energy as the input source. The output of the solar has been given to the quadratic boost converter (QBC). The energy from the quadratic boost converter is stored in the battery. When the laptop is going to be charged, the energy from the battery is stepped down using the Buck converter. The voltage regulation of the converter   is obtained   using inner current control loop and outer voltage control loop method. The simulation results are presented for the quadratic boost converter.
