Three-level inverter configuration with common- mode voltage elimination for induction motor drive
A scheme for a three-level voltage space phasor generation with common-mode voltage elimination is proposed. An open-end-winding induction motor, fed from both ends by two threelevel inverters, which are realised by a cascading two two-level inverter, is used in this configuration. The voltage space vectors of individual three-level inverters, which generate the same commonmode voltage in the i...
متن کاملFive-level inverter scheme for an induction motor drive with simultaneous elimination of common- mode voltage and DC-link capacitor voltage imbalance
Abstract: The simultaneous elimination of common-mode voltage and DC-link capacitor voltage imbalance is achieved in a five-level inverter scheme for an induction motor drive throughout its operating range. A dual five-level inverter-fed open-end-winding induction motor structure is used for the proposed drive. Initially, the operating limitations of achieving this dual task for the fivelevel i...
متن کاملSpace Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter
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...
متن کاملSliding Mode Control Technique for an Induction Motor Drive Supplied by a Three-Level Voltage Source Inverter
SLIDING-MODE control is a control technique used widely in electromechanical systems today [1–4]. It bases on using main characteristics of modern inverter semiconductor switches as Insulated Gate-Commutated Transistors (IGCTs) or Insulated-Gate Bipolar Transistors (IGBTs) that are operating in switch mode with distinctly higher switching frequency [5] than formerly used Gate-Turn-Off Thyristor...
متن کاملA Novel PWM Inverter Switching Strategy for a Dual Two - level Inverter Fed Open - end Winding Induction Motor Drive
Absrracl--A dual two-level inverter fed open-end winding induction motor drive is proposed in this paper. A total of 64 voltage space phasor combinations are possible in this scheme as each inverter produces eight voltage space phasors. The proposed scheme produces voltage space phasor locations similar to that of a 3-level inverter. In a 3-level Inverter the series connected DC link capacitors...
