Pulla Sravani Kumari , Kasthuri Gunavardhan

In this paper, the design methodologies are used to obtain the multiple outputs of DC-DC converter with a coupled inductor. The proposed system consists of single input of low voltage level, which can be boost into two different voltage levels. In this topology a coupled inductor with only one power switch is utilized for voltage clamping and soft switching operation. The two output voltages in this topology are obtained by limited components. The output voltages obtained are middle voltage and high voltage terminals are taken as power for a dc load applications. This topology is developed for high efficiency power conversion and two different voltages for dc loads. The proportionalintegral derivative (PID) controller is designed in DC-DC converter to reduce the rise time and steady state error, and is modelled using SIMULINK and simulation results are obtained. It is referred as single input multiple output DC-DC converter.
