The authors propose a technique for reactive power compensation using powerful regenerative controlled-speed synchronous motor drive (SMD) based on three-level (3L) neutral point clamped (NPC) active front-end rectifier (AFE) and voltage source inverter (VSI). review of technical solutions showed that the limitations transmitted in system under consideration still have not been studied. paper p...

Direct torque control (DTC) is one of the most prominent techniques used by permanent magnet synchronous motor (PMSM) drives in industry applications. Nevertheless, presence hysteresis controllers and inaccurate voltage switching table traditional DTC results higher flux ripple. This study proposes an enhanced functioned Surface-mounted PMSM (S-PMSM) drive with mitigation The operation relies o...

Reliability is a fundamental requirement in electric propulsion systems, involving particular approach studies on system failure probabilities. An intrinsic improvement to the involves introducing robust architectures such as fault-tolerant motor drives these systems. Considering potential for hardware failures, design will achieve reliability objectives without recourse optimized redundancy or...

This study aimed to develop a three-phase permanent-magnet synchronous motor drive system with improvement in current harmonics. Considering the harmonic components induced electromotive force of motor, offline response (EMF) was measured for fast Fourier analysis, main were obtained, and voltage required reduce corresponding direct (d-axis) quadrature (q-axis) axes calculated. In closed-loop c...
