Envelope model for resonant converters and application in LLC converters
2007 European Conference on Power Electronics and Applications, 2007This 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 ...

LLC resonant converter design for bendable power converter
2016 IEEE Applied Power Electronics Conference and Exposition (APEC), 2016In this paper, a design approach of LLC resonant converter with bendable transformer is presented. First, the electrical parameters of the LLC resonant converter are calculated based on the first-harmonic-approximation (FHA) equivalent circuit. Second, the bendable transformer design approach based on bendable transformer model gives the physical ...

A novel resonant LLC soft-switching buck converter
2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014A new LLC resonant DC-DC buck converter is presented. The employed multi-resonant tank provides soft-switching conditions for all semiconductor devices independent from the operating voltages and the load current. The proposed converter enjoys useful advantages such as low element count, unconditional soft switching operation, self short-circuit ...

A Hybrid Pulse Frequency Modulation Control Strategy for L-LLC Resonant Converter
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022The traditional control strategy for the L-LLC resonant converter is the synchronous unequal width pulse frequency modulation (SUW PFM). However, this strategy causes a large circulating power in the forward buck and reverse boost modes, especially when ...
