Abstract	In this work, we show that the fuzzy logic controller can be used to significantly improve the performance of a power supply regulator over conventional control techniques. The existing linear regulator circuit used in the current design has excessive overshoot and ringing in response to step changes, particularly during initial turn-on into a cold (very low impedance) filament. The linear regulator compensates for gradual changes in the load, but an external system must apply the reference voltage gradually to prevent excessive overshoot. For these reasons, a fuzzy controller is an excellent choice to provide the needed nonlinear regulation. This regulator is used in high power amplifiers produced by Thales Broadcast and Multimedia, a manufacturer of UHF television transmitters located in Southwick, Massachusetts.
