Abstract :
This paper presents a recent extension of averaging theory for power electronic systems to include feedback controlled converters. A ripple estimate is presented. New switching frequency dependent averaged models for PWM DC-DC converters are introduced. Two important benefits of these new averaged models are the correction of DC offset error in steady-state, and the modeling of switching frequency effects on closed loop performance and stability
