Abstract :
A fuzzy logic controller is given for general DC-DC converters. The controller rule base comes from knowledge of converter operation. By controlling the switching duty cycle, a DC-DC converter can track a time varying reference signal having bandwidth beyond 20 KHz. Thus, the converter can be used as a high efficiency linear power amplifier with almost zero phase lag. Moreover, this performance is maintained under unknown load changes. Simulation results are included
