摘要

Owing to limited computational resources and the very large difference between electrical and thermal time constants, simulation for resonantly operated DC-DC converters using physical or ideal switching model is very time-consuming or impossible. In this contribution, a novel thermal-electrical averaging model of resonantly operated DC-DC converters is proposed to reduce the computational burden and time consumption. The thermal-electrical model is based on extended describing function method. All required parameters for the thermal model can be obtained from the datasheets or on the website. The thermal-electrical models are applied in series-parallel resonant converters with LC-type and C-type output filters as examples, and verified by comparison with two standard simulation tools. The thermal-electrical modelling procedure proposed in this contribution can of course also be applied for other types of resonant converters, such as series resonant converter, parallel resonant converter and multi-phase resonant converter.
