Abstract

Described in This work is the design and implementation of a microcontroller-based fuzzy logic average current-mode control (ACMC) for DC/DC converters. A fuzzy logic ACMC boost converter operating in the continuous conduction mode has been designed using a PIC16C782 microcontroller. Design procedures and implementation issues are discussed. No complex algorithm is required to estimate the controlled current because of the on-board peripherals of the microcontroller. By using lookup tables and other techniques, the fuzzy logic algorithm is implemented on the microcontroller successfully. Experimental results are presented, and encouragingly demonstrate the performance that a fuzzy logic ACMC DC-DC converter can achieve.
