Abstract

This paper presents the large and small signal envelope models for switching networks and rectifiers with variable frequency phase-shifted control for resonant converters. The model can be used to quickly perform DC and AC analysis with SPICE-compatible soft tools for a converter with frequency control, duty cycle control and variable frequency and variable control. Then the large signal envelope model of a LLC converter is given, the DC and AC sweep results with P SPICE are presented, by which its characteristic can be analyzed. Finally the verified results are given.
