This paper presents an approach for generating small signal models of resonant converters focusing on the transformer-isolated dual active bridge series resonant converter (DABSRC) topology. The presented approach can be generalized to other active bridge resonant converters with one or more phase shift control inputs. Both steady state analysis and small signal modeling of the DABSRC are shown, and the resulting models are experimentally verified using a 1 kW prototype converter.

Abstract
This paper presents an approach for generating small signal models of resonant converters focusing on the transformer-isolated dual active bridge series resonant converter (DABSRC) topology. The presented approach can be generalized to other active bridge resonant converters with one or more phase shift control inputs. Both steady state analysis and small signal modeling of the DABSRC are shown, and the resulting models are experimentally verified using a 1 kW prototype converter.
