Analysis, Design and Simulation of 12v/24v Boost Switching Converter

The objective of this paper is to analyze, design and simulate the Boost (step-up) switching converter which is one of the main parts of solar electric system. The converter performance such as load voltage, currents in capacitor and inductor, ripples of voltages and currents, etc. are analyzed and derived under continuous operations. The design of the converter is performed to step-up the input voltage 12 v from the battery storage equipment to an output voltage of 24v which will be the input to the inverter in solar system. LTspice and MatlabSimulink programs are used to simulate the Boost switching converter operation using a very high speed MOSFET as a switch with 20 KHZ switching frequency. The simulated results are compared with theoretical and the percentage error is found to be very small.
