One important reason is its high control complexity. It is therefore relevant to propose a simpler but efficient modulation scheme, similar as three phase VSI modulators with the well-known symmetrical carrier-based ones. The modulation presented in this paper is equivalent to a particular Space Vector Modulation (SVM) and takes into account harmonics and unbalanced input voltages, with the same maximum voltage transfer ratio (86%). The aim of this work is to propose a simple and general pulse-width-modulation method using carrier-based modulator for an easier matrix converter control. Furthermore, a simple duty cycle calculation method is used, based on a virtual matrix converter. Finally, simulations and experimentations are presented to validate this simple, original and efficient modulation concept equivalent to matrix converter SVM.
ElectroMagnetic Interferences (EMI) filters are broadly used in power electronic systems in order to respect EMC normative constraints, which considerably increase overall cost and volume mainly because of the common-mode inductor. In this paper, a new method to calculate the optimal volume of the common-mode inductor is proposed. It takes into account core saturation issues that may greatly impact inductor volume and filter performances. Consequently, it is shown that in some cases, increasing the inductance value up to the best value can significantly reduce the filter volume in addition to further enhancing filter attenuation. It is also shown that different nearlybest inductor geometrical parameters with different shape factors can be obtained, which provides an important degree of freedom to designers while introducing the filter in the energy conversion system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
