This paper presents the study of maximum power point tracking (MPPT) controller implemented two phase soft-switched interleaved boost converter and focuses on the effectiveness of putting a solar panel instead of an ordinary dc source. The proposed system raises the overall efficiency by incorporating soft-switching technique in addition to MPPT. The algorithm used to track maximum possible power from the PV panel was variable step size algorithm, being superior over other methods due to its ability to change the step size according to the MPP. The above mentioned converter with MPPT is found to be highly efficient (around 96%) compared to other converters with MPPT because of reduced ripple and reduced switching losses. So it can be applied for high voltage as well as high power applications such as in space crafts, hybrid electric vehicles, dc back up energy systems, power factor correctors etc. It can also be used for grid connected and micro-grid applications because of low output voltage ripple. In this work, design and simulation has been done in MATLAB software to verify the performance of the converter with MPPT.
