Simulation Analysis of Voltage-Lift Type Boost Converter for Solar Photovoltaic System

Kalyani Sharma | Raj Kiran B.

Abstract: Solar photovoltaic (SPV) systems are now widely used to generate electric power for homes and commercial buildings. In photovoltaic based power system, power electronic interfaces are required for the efficient and reliable performance. This paper deals with photovoltaic based voltage-lift type boost converter for a standalone system. In this type of positive output dc-dc boost converters series voltage-lift technique is applied. Compared with the traditional boost converter, this converter can give dc-dc voltage with higher voltage conversion ratios. It is different from other existing dc-dc boost converters and is featured with the single-switch operation in simple structures. This voltage lift boost converter is connected with single phase full bridge inverter for AC system applications. In this paper simulation analysis of photovoltaic based traditional boost converter and voltage-lift type double and triple boost converter is done in MATLAB/Simulink environment. The simulation of boost converters integrated with single phase full bridge inverter and LC filter is also done. It is observed that with the use of voltage-lift type converters high voltages is obtained at output stage and with the use of LC filter more sinusoidal AC output voltage is possible and the power quality of boost converter fed photovoltaic standalone system is highly improved.
