“…These three phase currents include components located at fundamental grid frequency and higher frequencies. A High Pass Filter (HPF), whose transfer functions in continuous and discrete time domain are defined in (15) and (16) respectively, can be used to remove fundamental component and to obtain high frequency components which are responsible of supply current pollution. If these three phase currents idf(k+1) composed of high frequency components are subtracted from the supply current references, then this effectively reduces the magnitudes of high frequency harmonics in supply current and filter capacitor voltage.…”

“…In [14], in addition to conventional predictive approach for MCs, a cost term is added to cost function to reduce the number of commutations and consequently it decreases the switching losses. In [15], a method to decrease the computational burden of model predictive approach is proposed. This technique eliminates the prediction of threephase currents at sampling instant (k+1), and reduces the number of reactive power predictions and cost function evaluation from 25 to 10.…”

In this paper, a model predictive control (MPC) scheme is proposed to control indirect matrix converter (IMC), which is used for three phase-to-three phase direct power conversion without any intermediate energy storage component between them. The aim in the control of current source rectifier (CSR) stage of IMC is generally to have unity power factor with relatively low total harmonic distortion (THD). The aim in the control of voltage source inverter (VSI) stage is to be able to synthesize sinusoidal load currents with desired peak value and frequency. Imposed source current MPC technique in abc frame is used for the rectifier stage. An active damping technique without requiring the selection of an appropriate value for fictitious damping resistor is also included in the proposed control scheme in order to mitigate the resonance phenomenon of lightly damped input LC filter to suppress the higher order harmonics in supply currents. Load currents with desired peak and frequency are also obtained by imposing sinusoidal currents in abc frame. Two different cost functions are combined into a single cost function without any weighting factor since both error terms are in the same nature. The switching state that minimizes this pre-defined cost function among the 24-valid switching combinations of IMC is selected and applied to converter. The proposed model predictive control with active damping method shows a good performance in terms of THD levels in supply currents even at low current demands from supply side. The proposed strategy guarantees unity power factor operation and draws sinusoidal load currents at desired peak and frequency. Index Terms-Indirect matrix converter, ac-ac power conversion, model predictive control, active damping.

“…While the GaN-based VFDs (using a standard three-phase two-level voltage source inverter) are commercially available in the industry, a matrix converter is becoming a popular alternative for next-generation motor drive systems [3][4][5][6][7]. Figure 1 shows the typical two-level voltage source inverter and the matrix converter block diagram for the VFDs.…”

Gallium nitride (GaN) devices have been widely adopted to achieve high efficiency and high power density as alternative solutions to silicon devices. When the GaN power devices are used for variable frequency drive (VFD) systems, the high dv/dt pulses at the motor terminal, which induce shaft voltage and common mode current, should be carefully considered to ensure system reliability. Although the high dv/dt issues can be mitigated with a dv/dt filter method, it leads to performance degradation depending on cable length. Meanwhile, a matrix converter also becomes a next-generation power converter for the VFDs which has a regeneration capability and unity power factor. Thus, this paper discusses the GaN-based matrix converter for the VFD as a study case considering the motor terminal voltage quality and the common mode current. Also, a sine wave filter is adopted to cope with the terminal voltage quality irrespective of cable length. The optimized design procedure of the sine filter considers practical issues. Experimental results are presented to suggest a suitable solution for the GaN-based VFDs in accordance with the cable length.

“…In recent years, finite-control-set model predictive torque control (FCS-MPTC), which is considered as an alternative control strategy to DTC has been widely researched. It takes the advantage of the inherent discrete nature of power converters, predicts the future state of the system and select the optimal voltage vector which can minimize a predefined cost function [7][8][9]. In spite of advantages above, torque ripple and flux ripple are still inevitable for MPTC, since only one vector is selected during a fixed full control period.…”

This paper proposes an improved two-vector modelpredictive torque control (MPTC) strategy to reduce the average torque ripple and improve the flux tracking performance. When determining the duty ratio of vector combination, this method aims at restricting the root mean square (RMS) error of both torque and flux during the whole control period. Every vector combination and corresponding time duration are evaluated in the cost function, which leads to global restriction of torque ripple and flux ripple. In order to avoid increasing switching frequency and computational burden, a restriction is added on the second vector. The three candidates of the second vector are the two adjacent vectors of the first one and zero vector. Simulation results are provided to show the effectiveness of the proposed strategy.
