Modeling and simulation of interleaved Buck-boost converter with PID controller

In this paper, the analysis and modeling of interleaved Buck- boost converter with PID controller is discussed. Nowadays, Buck-boost power converter is widely used in many applications and power capability demands. The applications of Buck-boost power converter may be seen in electric vehicles, photovoltaic (PV) system, uninterruptable power supplies (UPS), and fuel cell power system. Converters are controlled by interleaved switching signals, which have the same switching frequency but shifted in phase. By paralleling the converters, the input current can be shared among the inductors so that high reliability and efficiency in power electronic systems can be obtained and ripples also reduced, the converter performance can be improved. The control circuit of this converter is controlled by using the PID controller. The simulation of interleaved buck-boost converter results with PID controller has been presented in detail.
