"Method of calculation of the inverter's input current harmonics by means of Bessel's function"




Mirosław Lewandowski - Warsaw University of Technology, Institute of Electrical Machines


In this paper analytical calculation method of inverter input current with usage of Bessel function of first kind is used. Described method allows to analyse the influence of particular voltage and current harmonics on inverter input current spectrum, in a rather simple way. In comparison, analysed circuit was simulated and inverter input current was determined. With usage of FFT spectrum of inverter current was determined for its time
course. Spectrums calculated with FFT and with described method was compared.
