Abstract
A novel control mode named SCM (skip cycle modulation) in switching DC-DC converter is developed and analyzed in this paper. The principles and the characteristics of SCM are described. Compared with PWM and PFM control modes, the response speed of DC-DC converter under SCM control mode is faster, the efficiency of the system with low loads is higher, and the harmonics smaller. All of these indicate that SCM is a better control mode in high frequency switching DC-DC converter.
