Abstract :
A comprehensive analysis of the high-frequency quasiresonant 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.
