“…Because at line frequency, the core cross section is large in order to generate large flux linkage. If the frequency of the excitation is increased the core cross-section area will be reduced by order of magnitude [22,27]. In order to generate high frequency excitation matrix converters are used, which converts the line frequency input to high frequency voltage by virtue of four-quadrant AC-switches [22][23][24][25][26][27].…”

“…Thus, the line frequency voltage at the utility is amplitude modulated by the high switching frequency of the matrix converter to excite the transformer [22][23][24][25][26][27]. In ideal transformer with zero leakage, the amplitude modulated voltage is reflected across the secondary winding of the transformer.…”

“…Thus, by increasing the excitation frequency by means of power converter systems, the transformer size can be reduced to a large extent. Different topologies of both DC links based and matrix converter based power-electronic transformers are available in literature [22][23][24][25][26][27]. In this paper, different topologies of matrix converter based powerelectronic transformers are investigated.…”

AC-AC converters (e.g. matrix converters) are mostly semiconductor solutions for applications where intermediate energy storage is eliminated. This paper summarizes the research done and being carried out at the University of Minnesota for applications in motor drives and power-electronic transformers with advanced features. This paper presents a carrier-based modulation method for matrix converters and its application during for both input unbalance and output over-modulation. Various topologies of matrix converter are described for both drives and power-electronic transformers. These topologies have some inherent benefits like common-mode voltage elimination across the bearings of the motor/generator and controllable power factor at the input side. Some of the described technologies require open-ended machines as load and thereby some advantages like enhanced output voltage (1.5 times the output of normal three terminal load) are achieved. 

“…In addition the variety of diameters and current ranges available allows the user to carry only one lightweight probe for a wide range of applications. So their use has increased very recently in applications of power electronics [6], relay protection, and power quality measurements [7] or transients [8−10]. At present electronic current transformers (ECTs) with a Rogowski coil have been developed, which bring simple insulation structures and excellent dynamic performances to electronic instrument transformers [11].…”

This paper describes the design and test of a new high-current electronic current transformer based on a Rogowski coil. For better performances, electronic current transformers are used to replace conventional electro-magnetic inductive current transformers based on ferromagnetic cores and windings to measure high-current on the high voltage distribution grids. The design of a new high-current electronic current transformer is described in this paper. The principal schemes of the prototype and partial evaluation results are presented. Through relative tests it is known that the prototype has a wide dynamic range and frequency band, and it can allow high accuracy measurements.

The development of power systems and the move to smart grid have increased the need for new technologies. In this regard, solid-state transformers have been proposed as a suitable alternative to conventional transformers. Solidstate transformers are among the equipment based on power electronic converters that in addition to better performance than conventional transformers provide a variety of other services. In this article, the concept and types of solid-state transformer topologies and configurations and their applications, especially in smart grid, are investigated. Studies show that the various characteristics of solid-state transformers have led to much consideration as potential transformers in smart grid applications, the integration of distributed generation sources, modern traction systems, and so on.
