Analytical Estimation Method of Winding Parasitic Capacitance for High-Frequency High-Voltage Application
Aiming to calculate the winding parasitic capacitance for high-frequency high-voltage application, this paper proposes an improved energy method by dividing the electrostatic field into several energy regions. Analytical models of the divided energy regions are established based on the assumed elect...

Aiming to calculate the winding parasitic capacitance for high-frequency high-voltage application, this paper proposes an improved energy method by dividing the electrostatic field into several energy regions. Analytical models of the divided energy regions are established based on the assumed electric field distribution. The stored electrostatic energy in the specified regions covers not only the energy between adjacent turns but also the non-adjacent turns, and a compensation factor is introduced to correct the layer misalignment problem of the standard winding, which makes the analytical energy fairly accurate. Following closely, a calculation procedure of parasitic capacitance is demonstrated. In the end, the accuracy and effectiveness of this method are verified by finite element simulations and measurements. |
