Generalized State-Space Averaging (GSSA) Techniques Applied on a Fuzzy Logic Controller for QRC's Converters

Abstract.
The design of fuzzy logic controller used to improve dynamical response of DC/DC Quasi-Resonant Converters (QRC's) that work with low switching losses is described in this paper. An averaged large signal circuit has been used to reduce simulation time. Compared to linear control techniques, the unlinear fuzzy logic control come with superior response parameters so if we look to apply this for an DC/DC system converters the price-quality compromise recommend the fuzzy logic controller. Computer simulations are used to verify the feasibility of the proposed fuzzy control.
