Abstract :
Power factor correction rectifiers have nonlinear characteristics. Analysis and design is very difficult based on nonlinear models. Piecewise affine(PWA) modeling is an approach for this purpose and design of controllers is straight for PWA models. The conventional PWA modeling has spikes of control signals in switching instances. It will remove by fuzzy-PWA modeling. In this paper, the fuzzy-PWA is introduced for precise modeling. The new modeling method is implemented on the boost power factor correction rectifier. Comparison of between fuzzy-PWA, conventional Piecewise affine and nonlinear models is done by simulations.
