Stabilization of Boost Converter Connected to Photovoltaic Source Using PID Controller

The switched converter is widely used in distributed generation systems. The most popular standalone power generation system is based on solar energy. The isolated photovoltaic (PV) system is applicable to the low power application. In this paper, voltage stabilization of Boost Converter connected to photovoltaic Source using PID Controller is analyzed. Boost converter is fed from conventional solar PV system of 12 V. The output voltage of the converter is stabilized by controlling the on-time and off-time of the switch connected in boost converter. The non-linear behavior of the converter is approximated by using the averaging technique in state-space model. PID controller is tuned by Zeigler–Nichols method and all the results are obtained using Simulink platform of MATLAB. DC–DC boost conversion technique finds wide applications in uninterrupted power supplies, electric vehicles, HVDC, photovoltaic systems, etc.
