Abstract:
A mode to calculate distributed capacitances of inductances coil was suggested. Analysis based on effective circuit shows that the interlayer capacitance was the main part of the distributed capacitance of inductor coils. According to the principle of the energy of electric field determined by the electric field distribution,the electric field energies of both kinds of coils winded with "Z" and "U" types were analyzed,and their expressions of the equivalent distributed ca鄄 pacitances derived,respectively. Through the comparison of experimental results with that of the calculation,the mode was proved to be correct. The expression was simple and easy to use for the design of inductors and filters,as well as the estimation of the distributed capacitance of transformer,etc.
