Average current-mode control for a boost converter using an 8-bit microcontroller

This paper presents hybrid average current-mode control (ACMC) for a boost converter using an 8-bit microcontroller. In order to demonstrate the feasibility of a hybrid ACMC DC-DC converter, an ACMC boost converter operating in the continuous conduction mode has been designed using a PIC16C782 microcontroller. System modeling, main design procedures, as well as some hardware and software implementation issues are discussed. Experimental results are presented, and encouragingly demonstrate the performance that a hybrid ACMC DC-DC converter can achieve. A pure analog controller using a UC3K86 analog control chip from Texas Instruments has also been implemented for comparison.
