In this paper, a comparative evaluation of two modelling tools for switching AC-AC power converters is presented. Both of them are based on average modelling techniques. The first approach is based on the circuit averaging technique and consists in the topological manipulations, applied to a converter states. The second approach makes use of a state-space averaged model of the converter and is based on analytical manipulations using the different state representations of a converter. The two modelling techniques are applied to a same AC-AC called matrix-reactance frequency converter based on buck-boost topology. These techniques are compared on the basis of their rapidity, quantity of calculations and transformations and its limitations.

Email: P.Szczesniak@iee.uz.zgora.pl INTRODUCTIONModelling a power electronic converter is a complex issue due to the fact of digital control complexity and high number of power converter components. Furthermore, given the increasing number of different modulation strategies, it is necessary to study their impact in converter operation. In order to achieve their goal power converters must be appropriately modelled in simulation or analytical studies. Hence it is necessary to create simple models. The problem has been largely studied and a wide variety of models have been proposed [1]- [6]. However, the use of those models and their simulation in a computer still requires a large amount of resources and circuit simplification and mathematical transformations. In this paper, a comparative evaluation of two modelling approach of complex direct AC-AC frequency converters is presented. The presented modelling methods are based on circuit averaging technique [1], [5] and statespace averaged model [5].The change of frequency in AC voltage is now one of the important functions of solid state power converters. The most desirable features of frequency converters include the possibility of generating load voltages with arbitrary amplitude and generating sinusoidal source and load currents and voltage waveforms, the possibility of providing unity power factor for any load, and finally, their construction using a simple and compact power circuit. The past few years have witnessed remarkable progress in research into direct power AC-AC frequency converters without a DC energy storage element. Many exciting applications have been developed [7]- [12]. The most common is the matrix converter (MC) topology [7]. Another group of AC-AC frequency converters with a buck-boost voltage transformation possibility and without DC energy storage is proposed in [10]-[12], and are known as matrix-reactance frequency converters (MRFC).

“…Another emerging technology for power systems is the matrix converter [9], which also has potential in applications with renewable resources and smart-grids [10][11][12] as it can convert energy like a classic transformer but also offers other advantages such as control of bidirectional power flow and better isolation [13,14]. Previous studies have already experimented with a matrix converter [15] and AC conversion [16], and the combination of both in a single apparatus is a natural extension of this research.…”

The Three-Phase Power Router and Its Operation with Matrix Converter toward Smart-Grid Applications

et al. 2015

A power router has been recently developed for both AC and DC applications that has the potential for smart-grid applications. This study focuses on three-phase power switching through the development of an experimental setup which consists of a three-phase direct AC/AC matrix converter with a power router attached to its output. Various experimental switching scenarios with the loads connected to different input sources were investigated. The crescent introduction of decentralized power generators throughout the power-grid obligates us to take measurements for a better distribution and management of the power. Power routers and matrix converters have great potential to succeed this goal with the help of power electronics devices. In this paper, a novel experimental three-phase power switching was achieved and the advantages of this operation are presented, such as on-demand and constant power supply at the desired loads.
