This doctoral thesis deals with the development of a layout-based analytical model for the design of monolithic thick film transformers for power transmission based on new LTCC (Low Temperature Cofired Ceramics) technology.
The simulation results are validated by measurement data of the prototype transformers. As a key result, a new gap transformer has been developed transmitting 101W for an effective input voltage of only 20V at 50Ω load and an efficiency of 95.3%, a small volume of only 0.3cm³ and a frequency of 2.5MHz. This transformer performance exceeds the expected specifications.
With the model developed in this thesis, parameters can be varied easily and component designs can be optimized. Some further aspects of designing planar transformers are discussed to give a complete overview.
