A Hard- and Software Co-simulation Model of a Matrix Converter

Matrix converters are said to be integrable in smaller installation areas rather than DC-link converters due to the absent DC-link capacitor. In return the matrix converter may require input filters larger in size compared to the DC-link converter to suppress the power grid perturbations with the objective of keeping the perturbations below the normative regulated limits. Henceforth, a fair handed comparison has to be performed for the input filters' installation spaces of both converters investigated on a common basis of comparison. As the the power grid perturbations of both systems have already been presented in a prior work as well as a generic filter calculation method, which fits both systems, in this paper the absolute values of the input filters are introduced for the full normative frequency range. Dilating the prior presented results, a method for varying the PWM frequency in a very calculation time saving way is presented for so-called pseudo-spectra, contain ing the maximum values of the amplitudes occuring under permutation of the spectra influencing parameters

Matrix converters are said to redeem the very well established DC-link converter in some fields of application. One general idea behind the matrix converter approach is the absent DC-link capacitor which is referred as one reason for the matrix converter being superior to the DC-link converter regarding its size and lifespan. On the other hand, the input filter of the matrix converter is said to be larger than the input filter of DC-link converters undermining the afore mentioned advantage of the matrix converter concerning the size. In this paper a general approach regarding the input filter design is applied to both converter types to perform a fair-handed filter comparison which also takes into account the parasitic series resistances of the reactances. A first theoretical investigation based on a simplified spectrum is performed for a DC-link converter and a matrix converter both designed for 3 kVA apparent output power
