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 36o 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

Abstract

Direct current (DC) electronic load is a useful equipment for testing the electrical system. It can emulate various load at a high rating. The electronic load requires a power converter to operate and a linear regulator is a common option. Nonetheless, it is hard to control due to the temperature variation. This paper proposed a DC electronic load using the boost converter. The proposed electronic load operates in the continuous current mode and control using the integral controller. The electronic load using the boost converter is compared with the electronic load using the linear regulator. The results show that the boost converter able to operate as an electronic load with an error lower than 0.5% and response time lower than 13 ms.
