Abstract :
A comprehensive analysis of the high-frequency quasi-resonant buck converter is presented using the graphical state-plane technique. The analysis has revealed, for the first time, the presence of several unfamiliar modes of operation. The voltage conversion ratio and boundary switching frequency for each mode are derived. The existence of various operating modes are verified experimentally.
