“…Moreover, the DC-link capacitor has a low life span and high sensitivity to temperature; it finds limited application in deepsea exploration, aeronautical engineering, and hybrid electric vehicle. For these applications, the MC gives the anticipated output frequency and voltage control without a capacitor, unlike back-back AC-AC converters [10][11][12][13]. In a direct MC, the absence of a DC storage capacitor makes it compact and suitable for the above applications [14][15][16].…”

The multiphase matrix converter outperforms the conventional three‐phase system with higher fault tolerance capability and higher power control competency. This paper discusses the direct control based on different possible switching combinations of a three‐phase to five‐phase matrix converter (MC). The proposed control topology significantly reduces the switching commutations in a switching cycle when compared with its counterpart. The control is based on the modified space vector pulse width modulation (SVPWM) strategy. The proposed space vector scheme intelligently selects the voltage vectors to get the desired output characteristics with the least possible switching transitions in a switching cycle. Three possible cases exist in controlling space vectors based on their magnitude, the number of active switching vectors, and their commutations. The results for three different cases of SVPWM have been presented and compared. The total harmonic distortion (THD) obtained in the output is lower in case 2; however, it suffers from a higher common‐mode voltage (CMV). The scheme has been successfully implemented and verified in hardware.

“…However, they need a wide source filter inductor resulting in low reliability, high price, and wide size [6,7]. Nowadays, matrix converters (MC) are more popular due to several interesting gains, like sinusoidal input/output waveforms, bi-directionality power flow, input unity power factor, and the absence of the dc link [6][7][8][9][10]. A direct matrix converter (DMC) can be used to control the DFIG instead of the classical back-to-back converters, as depicted in (Fig.…”

This paper proposes a robust decoupling power algorithm based on a doubly fed induction generator (DFIG) for variable speed wind-turbine (WT). The DFIG rotor circuit is fed by the direct matrix converter (DMC), which presents several features such as no need to the dc-bus voltage, sinusoidal supply, rotor side waveforms, bidirectional power flow, and adjustable input power factor. The 18 bidirectional switches are controlled using the Venturini modulation technique. On the other hand, the DFIG stator circuit is connected directly to the grid. The nonlinear control strategy based on feedback linearization is applied to control the stator power (Ps and Qs) independently using the rotor quadrature and direct currents (irq and ird), which present the images of the previous stator powers. Some limitations appear in the power algorithm using the conventional pi controller, especially in power tracking, error, and quality. In this context, the model reference adaptive controller (MRAC) presents an alternative solution, a robust and efficient controller proposed instead of the pi controllers to control stator powers. Finally, the simulation results confirm that the proposed algorithm could work under hard conditions and demonstrate that the wind energy conversion system (WECS) provides enhanced dynamic responses in transient and steady states and good power quality delivered to the grid.
