Development of the Program for Calculation of Losses of Electric Capacitors in Non-Sinusoidal Modes of Operation

Due to the need for simplifying design and optimization processes of electrical capacitors with specified parameters, this work was aimed at research of specialized software for calculating losses in capacitors under non-sinusoidal modes of operation. During the creation of the program, the program code was written in the Python programming language and created graphical application for the convenience. For approbation of the program frequency spectra of capacitance and loss tangent of metal-film capacitor were measured and used for calculation the power of thermal losses, that was taken for the simulation in Comsol software. Simulation results were compared with experimental ones. The result of work is program for calculating capacitor losses under non-sinusoidal operating conditions. The software will simplify the design process of electrical products and simplify stages of development and calculation losses of capacitors designed to operate in non-sinusoidal modes.
