Abstract
This article presents a new method for high voltage capacitor design that utilizes barium titanate which has a high permittivity specification value, instead of common insulators. The main purpose is to define a full electrical model which considers the effects of temperature and electric field values on tanδ and permittivity calculations. The main challenge is that the dielectric constant varies during the process and a hysteresis loop exists in which the dielectric constant and dissipation factors change with temperature variations; a detailed analysis of which is presented in this article. This investigation also leads to realizing the application of new ferroelectric insulators in modern high voltage capacitors.
