Abstract In this paper named ‘SEPIC-Boost CSCCC-based SPWM Inverter with MPPT Technique’ a new design is proposed which uses PV panel to extract power from solar energy. Its main aim is to extract power from single solar PV panel for MLI. It also uses a SIMO-SEPIC-CSC combination converter in between the PV panel and the MLI. As the conventional methods, two-staged power conversion is implemented and along with this, it has a SIMO-SEPIC-CSC combination converter to generate inverter input. To improve efficiency and make it more reliable, MPPT tracking is employed which helps in drawing of maximum power from the PV panel. Simulation is done in MATLAB/Simulink 2016A. Results are displayed as a verification of the proposed idea. Keywords PV panel · MLI · MPPT · SIMO-SEPIC-CSC combination converter
1 Introduction In terms of power generation compared to any other forms of renewable energy resource, solar panels are more frequently used. This popularity of the solar energy owes to the fact that it is plenty and hence is freely available also that it is void of pollution and noise. There is also a high increase of the rate of usage [1]. There are three stages for generation of power, i.e., solar energy is sent for the DC-to-DC conversion which is in turn sent for the DC-to-AC conversion [2]. Other D. Banerjee (B) · R.

proposals include mainly two stages of conversion which uses DC-to-AC conversion from solar energy with a DC-link capacitor used in between the two stages [3, 4]. This has a disadvantage in which the equipment is made expensive and heavy which is unsuitable for any types of applications. In a multilevel inverter from only one solar panel, seven levels can be developed. An inverter consisting of nine levels can also be developed but there is a disadvantage of asymmetrical configuration leading to uneven switch stress [5]. As the total number of levels of the voltage increases the number of solar panels required also increases which make the design heavy and expensive added to which MPPT algorithm is used to all the panels which create several problems. Unbalance in current and voltage occurs when distributed MPPT algorithm is implemented [6, 7]. For step up or step down of the voltage or current, DC-to-DC converter is used which naturally includes boost converter or buck-boost converter or SEPIC converter and many others. Combination of
