Abstract :
Small-signal models of quasi-square-wave (QSW) converters are obtained by using state-space averaging. These models are used to perform a comparative study which shows that current-mode control of QSW converters does not provide the improved dynamic performance with respect to voltage-mode control that can be found in the case of PWM and quasi-resonant converters
