Frequency Domain Analysis of Space-Vector PWM Four-Switch Voltage Source Inverter

Popis výsledku v původním jazyce

The paper presents harmonic analysis of the space vecto PWM waveform of the four-switch voltage source inverter feeding an induction motor drive. The analysis is based on a novel decomposition technique and on the Laplace transform of the voltage space vector. As the phase voltage are in principle asymmetrical, first the asymmetrical space vector sequence is expressed in symmetrical form. It is shown that the asymmetrical space vector sequence can be expressed with two symmetrical sequence. First sequence has vectors that are mutually shiffed by 60° as in conventional inverter, and second sequence has vector shifted by 180° and amplitudes are one half of the first sequence. Then the Laplace transform of the symmetrical space vector sequence is expressed. using the relation between the Laplace transform of the periodic wavwform and Fourier coefficients we can find the coefficients of the Fourier series. From the analytical relations we can derive harmonic spectra for defferent space vec
