The inverter is a major component of a renewable energy system and its performance affects the overall performance of the system. For typical household applications in remote areas, often there is need to operate at low power conditions where inverter efficiency can drop dramatically. Efficient operation at low power is important especially for stand-alone applications in developing countries where...
In this paper, the switching losses of matrix converters (MCs) using various commutation methods are calculated with MATLAB/Simulink. The commutation methods of 2-steps current commutation, 4-steps current commutation, 2-steps voltage commutation, 4-steps voltage commutation, and 3-steps voltage current commutation are treated. This paper compares their switching losses and discusses their differences.
To achieve high efficiency without performance deterioration is a desired objective in power conversion. This work presents a novel method to reduce switching losses, based on predictive control, which can be applied to a wide variety of switched-mode power converters. The idea is to predict switching losses for every valid switching state of the converter if applied during the next sampling time...
