Performance analysis of LTCC transformers for application in DC/DC converters

In this paper, a novel design of a LTCC (low temperature co-fired ceramics) transformer for application in DC/DC converters is proposed. The transformer possesses a compact structure with the coils surrounded by dielectric (or ferrite) material and between the coils one dielectric layer is placed. Simulation and measuring results for inductance, coupling coefficient and quality factor of the proposed transformer are also presented. Testing LTCC transformer characteristics is illustrated using a forward type of DC/DC converter.
