Reduced Order Modeling of Linearized Power Electronic Cricuit
Abstract
Most of the systems in our daily life consist of power electronic circuits. They are micro circuits which are difficult to be analyze because the circuit consists of nonlinear elements. This paper deals with one of the power electronic circuit, boost converter. The non-linear elements of the converter circuit are linearized. The obtained linearized converter circuit is a higher order model. Designing a controller for this higher order model is complex and simulation time also increases. So, efficient order reduction techniques have been used to reduce the system order. The models are simulated using MATLAB 13.0 simulink software. Simulation results show that hankel was a better method for order reduction depicting same characteristics for higher and lower order models.
