| Abstract |
This paper presents a numerical approach for determining the theoretical harmonic components ofunconventional pulse width modulation (PWM) strategies such as the Unified-Double Carrier PWM (Uni-DCPWM). The method uses a double Fourier integral formulation to analyze the inverter DC-link current harmoniccomponents, by establishing inner and outer integral limits of this formulation. The provided results of theinvestigated modulation strategy are demonstrated by comparing with those obtained by Fast Fourier Transform(FFT) analysis of simulated switched waveforms for selected conditions. 3D graphics and generalcartographies for global variation of the DC bus RMS current are also presented, together with acomparison of the harmonic performance of a classic PWM strategy and the Uni-DC PWM. |
