Coreless Planar Transformer using Low-Temperature Co-fired Ceramics for Isolated Gate Driver Applications

The aim of this thesis project is to design a signal isolation transformer for gate driver applications using coreless planar transformers (CPT) on a low-temperature co-fired ceramic (LTCC) substrate. To achieve this goal a modulator-demodulator circuit will be selected from several existing designs and an isolation transformer will be designed as a CPT to produce a high frequency high temperature signal isolation for gate driver applications in switching converters, audio drivers, and motor drives. Several designs for coreless planar transformers will be evaluated and tested, and the results will be compared to the theoretical performance obtained from SPICE models for each transformer design
