Analysis, design and implementation of the space-vector modulator for forced-commutated cycloconvertors

Implementación del Algoritmo Sünter-Clare en un Convertidor Matricial 3x3

“…Las tarjetas del CM y de la FPGA fueron diseñadas en la Universidad de Nottingham, en el Reino Unido (Huber et al, 1992) y fue adquirida para la realización de este proyecto. La tarjeta de comunicación HPI permite la transmisión de datos entre la PC y el DSP utilizando un puerto USB, con lo quees posible monitorear las diferentes variables, por medio de una interface desarrollada en Matlab.…”

Unified Power Flow Controllers Without Energy Storage: Designing Power Controllers for the Matrix Converter Solution

“…A digital signal processing (DSP) was used to implement the designed linear controllers for matrix vector selection at successive time steps. To achieve safe commutation between matrix converter bidirectional switches, the four-step output current strategy was used (Huber et al, 1992). This commutation process was implemented in a field programmable gate array (FPGA) included in Fig.…”

Space Vector Modulation for a 4-Leg Matrix Converter

“…At around the same time, a number of papers by Huber and Borojevic were published, which presented a new space vector modulation technique for the matrix converter [7][8][9][10]. This like the Alesina\Venturini Optimum method, was able to produce the theoretical maximum output voltage.…”

“…While the Space Vector representation had previously been used for inverter control it was not until Huber and Borojevic in 1989 [7][8][9][10] where this method was proposed for use with matrix converters. This was then extended with a paper by Casadei at al in 2002 [3,4], giving a full Space Vector Modulation strategy that controlled both the output voltage and input power factor.…”

“…Extending this in the case of the matrix converter would result in a 3x4, or four-leg, matrix converter as shown in With the introduction of the fourth leg, this adds another output variable that needs to be controlled, and so the modulation techniques why apply to the 3x3 matrix converter [3][4][5][6] are no longer valid, and so a new modulation strategy needs to be formulated for this new arrangement. After the work by Huber and Borojevic [7][8][9][10] and later Casadei [3,4] on adapting space vector modulation (SVM) for use with the 3x3 matrix converter, and then Ryan and De Doncker [11,12] along with Zhang at al [2,13,14] for the work on 3-dimensional SVM for the 4-leg inverter, these both proved as useful pointers towards how a successful technique could be derived for the 4-leg Matrix Converter. Therefore, this work sets out to explore the design of a Space Vector Modulation technique that is capable of controlling a 4-leg matrix converter, and then goes on to detail the building and testing of such a converter.…”
