Abstract
This paper presents a new switching method for Cascaded Multilevel Inverter (CMI). The new method uses multiple non-sinusoidal signals as the modulating signal. The main advantage of using non-sinusoidal modulating signal is that it provides higher fundamental component but at the cost of having a numbers of low-order harmonics in its unfiltered output voltage; naturally contributed by the non-sinusoidal modulating signal. In this paper, the Trapezoidal waveform is employed as the non-sinusoidal modulating signal for the CMI. Its harmonics profile of different slope angles is analysed. From the analysis, it was found that the trapezoidal with the slope angle of 36 o eliminates the third and fifth harmonics yet yields a high fundamental magnitude. To verify, a single-phase CMI prototype is constructed and an ALTERA FPGA is deployed to implement the proposed method’s algorithm. From the results, it was shown that analysis is validated DOI: http://dx.doi.org/10.11591/telkomnika.v10i4.855
