description DC - DC converters are the most widely used circuits in power electronics. They can be found in almost every electronic device nowadays, since all semiconductor components are powered by DC sources. DC-DC converter usually consists of power semiconductor devices which are operated as electronic switches. Operation of the switching devices causes the inherently nonlinear characteristic to the dc-dc converters including the buck-boost converter. Proportional-Integral-Differential (PID) controllers have been usually applied to the dc-dc converters because of their simplicity design. However, implementations of this control method to the nonlinear system such as the buck-boost converters will suffer from dynamic response for the converter output. To achieve a stable and fast response, nonlinear controller were applied to control buck-boost converters. Gaussian Fuzzy Logic Control (GFLC) was designed for the buck-boost converters.
