Space Vector Pwm Control of Dual Inverter Fed Open-end Winding Induction Motor Drive
scheme proposed here makes the individual inverter A space vector PWM technique is developed based switching frequency equal to half of the motor phase on the combination of space vectors from dual inverters switching frequency. %is results in low inverter switching feeding the induction motor from both ends (open-end with reduced power circuit complexity when compared to winding without neutra...
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...
متن کاملA harmonic elimination and suppression scheme for an open-end winding induction motor drive
In this paper, a harmonic elimination and suppression scheme for a dual-inverter-fed open-end winding induction motor drive is presented. Two isolated dc-link sources with voltage ratio of approximately 1 : 0.366 are required for the present drive. These two isolated dc links feeding two inverters to drive the openend winding induction motor eliminate the triplen harmonic currents from the moto...
متن کاملOpen-End Winding Induction Motor Drive Based on Indirect Matrix Converter
Open-end winding induction machines fed from two standard two-level voltage source inverters (VSI) provide an attractive arrangement for AC drives. An alternative approach is to use a dual output indirect matrix converter (IMC). It is well known that IMC provides fully bidirectional power flow operation, with small input size filter requirements. Whilst a standard IMC consists of an AC–DC matri...
متن کاملSwitching Algorithms for the Dual Inverter fed Open-end Winding Induction Motor Drive for 3-level Voltage Space Phasor Generation
An open-end winding induction motor, fed by two 2-level inverters connected at either end produces space vector locations, identical to those of a conventional 3-level inverter. In this paper, two switching algorithms are proposed to implement space vector PWM for the dual inverter scheme. The proposed algorithms do not employ any look-up tables. The time consuming task of sector identification...
