Analysis of Effective Parameters Sensitivity of Stray Capacitance of the MCG Generator Having One Turn

This paper presents a comprehensive procedure for Analysis of effective parameters sensitivity of the Stray Capacitance of high-voltage and high-frequency MCG generators and identifies all the factors that dictate the electrical behavior of these components. In the design process of the helical flux compression generators it is necessary to determine the initial inductance, resistance, and stray capacitance of it. Many methods exist whereby the inductance and resistance of a helical generator maybe calculated. But in this paper we are discussed analysis of effective parameters sensitivity of stray capacitance of one turn from coil of single-layer, multi-filament of helix magneto cumulative generator (MCG). Method presented in this paper is based on an analytical method and geometrical structure of singel-layer wires filaments in a turn of generator coil. This presented analytical theory is correct to calculate stray capacitance of one turn of coil with conductors wires filaments (CWsF) having circular cross-section that wounded around of the liner perfectly uniformly with a certain distance from surface of the cylindrical metal liner which is placed axially in the center of the coil. In the end, the sensitivity coefficients ratios of effects parameters are discussed and analyzed. Finally we will see that in order to decrease total stray capacitance of k-conductors wires filament (k-CWsF) in a turn of MCG coil we should increase air gap between CWF and central cylindrical liner , and insolating coating thickness of CWsF in inside generator coil and also decrease diameter of CWsF cross-section and length of CWsF turn of coil.
