Description
Summary:This paper presents an optimal design methodology of monolithic high-voltage (HV) pulse transformers based on the direct 2-D finite-element analysis (FEA) identification of the electrical equivalent circuit parameters without any simplified analytical modeling. This method is applied to the preliminary optimal design of the monolithic HV pulse transformer for the future compact linear collider modulators under study at CERN. The feasibility of such a transformer with tight specifications is demonstrated. The predicted performance obtained with the direct 2-D FEA optimization process is validated by 3-D FEA simulation. The dimensioning model based on the direct 2-D FEA identification of the electrical equivalent circuit parameters is validated on a prototype.
