Design, Modeling and Analysis of Two Level Interleaved Boost Converter

The two level interleaved boost converter (IBC) for low input voltage (battery or photovoltaic) applications. The steady state performance of the interleaved boost converter is investigated by MATLAB/simulation. The IBC is designed for low input voltage applications. The modeling and analysis is carried out considering the parasitic elements of all the elements and devices. The IBC is modeled and analyzed using state space averaging technique and analysis is carried using small signal analysis. Two level IBC is analyzed considered continuous inductor current and duty ratio greater than 0.5. The analog PID controller is designed based on the design parameters of the converter and simulated in open loop and closed loop.
