Influence of the stator current reconstruction method on direct torque control of induction motor drive in current sensor postfault operation [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2022 Modern induction motor (IM) drives with a higher degree of safety should be equipped with fault-tolerant control (FTC) solutions. Current sensor (CS) failures constitute a serious problem in systems using vector control strategies for IMs because these ...

Virtual flux vector reconstruction of a PWM rectifier
工程科学学报, 2016 The virtual flux space vector of a pulse width modulation (PWM) rectifier usually can be calculated by integrating the grid voltage vector. In practice, the pure integral part is replaced with a first-order low-pass filter (FOLP) to counteract the DC ...

Study on the space vector modulation strategy of matrix converter under abnormal input condition
Alexandria Engineering Journal, 2022 Since the matrix converter (MC) has no intermediate DC energy storage link, any disturbance at the input will affect the output. To guarantee the safe and stable operation of MC system, a feed-forward compensation (FFC) strategy for MC operation in ...

Reduction of DC Current Ripples by Virtual Space Vector Modulation for Three-Phase AC–DC Matrix Converters [PDF]
Energies, 2019 In this paper, the virtual space vector modulation for the AC–DC (alternating current–direct current) matrix converters is proposed to reduce the DC current ripples in the whole modulation index range. In the proposed method, each virtual vector is synthesized by the two nearest original active vectors.

Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters [PDF]
, 2016 This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference frame phase locked loop (PLL).
