Abstract :
The small-signal behavior of a frequency controlled resonant converter is modeled as an equivalent pulsewidth modulation (PWM) converter. By this model, a recently developed simulation algorithm for PWM converter is modified to simulate both the open-loop and closed-loop small-signal behavior. Experimental results show that this approach is accurate and efficient.
