In this paper we consider linear, lumped, finite networks composed of interconnections of time-variable and passive resistances, capacitances, inductances, gyrators and transformers. We assume an impedance matrix port description of the network is given and solve the problem of synthesising the impedance, that is, we determine a set of passive elements and a scheme of interconnection which yiel...

This paper presents a method of the determination of a positive stable realisation of the fractional continuous-time positive system consisting of n subsystems with one fractional order and with different fractional orders. For the proposed method, a digraph-based algorithm was constructed. In this paper, we have shown how we can realise the transfer matrix using electrical circuits consisting ...

Abstract—In this paper, we consider the resistances and inductances extraction from finite conducting metals. To remedy the weakness of volume integral equation, we extend the usage of a surface integral equation method from analyzing finite conducting rectangular wire strip to analyzing arbitrarily shaped geometry. Moreover the multilevel Green function method (MLGFIM) with a complexity of O(N...

Typically, inserted-shunt integrated transformers have symmetric primary and secondary leakage inductances. However, bidirectional resonant converters typically operate more efficiently with different series In this paper, a new topology for an transformer which can provide tunable, asymmetric (series) inductances on the sides is presented. Two magnetic shunts, appropriate air gaps, are inserte...

The study introduces the detailed sequence of operations necessary to determine the selfand mutual inductances of power transformers from numerically simulated open-circuit and bucking experiments. Parameters of a welding style transformer are compared to those of a normal step-down transformer of equivalent ratings. The investigation identifies the different patterns of magnetic flux circulati...
