Abstract :
Tins paper presents envelope model of frequency- duty-controlled LLC converters. With this model, its DC and AC characteristics can be quickly simulated. Moreover, its transfer functions have been solved and analyzed. Thus, the compensator with duty cycle control, variable frequency control, or variable frequency variable duty cycle control can be easily designed using this model.
