This paper shows that the large signal behavior of high power factor ac to dc power conditioners can be analyzed via linear models, by using squared output voltage as the state variable. The state equation for general loads e.g. constant power plus resistive is obtained by a simple dynamic power balance. Time invariant or periodically varying controllers, acting at the time scales of the line or switching periods respectively, are then easy to design from the resulting averaged or sampled data models.
