Abstract

Sensorless peak current mode (SPCM) controlled quadratic boost converter is studied in this paper. Compared with conventional peak current mode control using the switching current for feedback variable, SPCM control reduces control complexity without current sensing, and enhances noise susceptibility. The sub-harmonic oscillation existed in the SPCM controlled quadratic boost converter is investigated, which can be effectively eliminated by using slope compensation when the slope of compensation equals to down slope of inductor current. Experimental results are given to verify the validity of the theoretical analysis.
