For heavy industrial drive applications, the direct matrix converter (DMC) solves problems caused by two-stage power conversion mechanism. Due to a lack of technological advancement, control multiphase drives operated DMC is significant cause concern. This article thus presents torque (DTC) scheme based on space vector pulsewidth modulation (SVPWM) for five-phase induction motor (FPIM) driven t...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

In this paper a fractional order PI controller (FOPI) is proposed for the speed control of Permanent Magnet Synchronous Motor(PMSM). Fractional calculus is introduced into the PI controller, and proposes a robust fractional order PI controller (FOPI) for the speed control of a PMSM .PMSM drive system is a nonlinear system which is sensitive to load disturbance, parameter variation, unmodelled a...

In this paper, a comparative study is carried out between the carrier (SPWM), third harmonic injection (THIPWM), and space vector (SVPWM) modulation schemes in terms of conducted (common and differential modes) and radiated electromagnetic interference (EMI) generated by three-phase two-level voltage source inverters. For this purpose, an experimental setup of the converter feeding an induction...

Abstract— Multilevel inverters have gained importance in medium voltage and high power drives applications due to superior performance over two level inverters such as lower harmonics, less voltage stress, better harmonic profile, reduced dv/dt stress, produce lower common mode voltage etc., This paper focuses on implementation of Space Vector Pulse Width Modulation (SVPWM) Technique for Three ...

Active power filter (APF) using novel virtual line-flux-linkage oriented control strategy can not only realizes no phase-locked-loop (PLL) control, but also achieves a good inhibitory effect to interfere. However, there are some problems in the conventional method, such as the error of amplitude, the shift of phase angle and the non-determinacy of initial oriented angle. In this paper, two one-...

Abstract-The STATCOM (STATic synchronous COMpensator) is increasingly popular in Power System applications. In general, power factor and stability of the utility system can be improved by STATCOM.Specially, STATCOM can stabilize a given node voltage and compensate the power factor of the system and also load by that node. The steady state and dynamic performance of STATCOM are very critical to ...

in order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. the shore power supply which needs transferring 380v/50hz to 450v/60hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...

A modular multilevel converter (MMC) can generate different common-mode voltage (CMV) values due to the high-frequency changing of switching state under various modulation strategies. The dv/dt will produce current in equivalent loop ground, which affect insulation and shorten life equipment. To eliminate effect on MMC operation, a elimination strategy (0CMV-SVPWM) is proposed for five-level sp...

For high-power converters, the low switching frequency (SF) modulation represented by selective harmonic elimination pulse width (SHE-PWM) is crucial to reduce loss and enhance efficiency with a good steady-state performance. However, since advantages of SHE-PWM mainly come from fixed angle distribution limited non-linear equations, angles should be adjusted slowly. This requires that bandwidth...
