Abstract
In this paper a novel approach for dual boost converter is presented which is applicable to transformer less grid linked inverter. The input voltage from solar modules given to boost converter should be fixed. But due to environmental causes it varies. For a certain range of variations in input it is controlled by controlling the PWM triggering of MOSFET in boost converter circuit so that the output of the boost converter is a fixed output. This approach is analyzed, designed and simulated using MATLAB/SIMULINK, curve fitting in MATLAB and generating formula, implementing the formula using VHDL on Spartan 3 FPGA and also on AVR microcontroller.
Keywords: Dual Boost Converter, Duty Cycle, Pulse triggering
