<span lang="EN-US">The Nine-Switch Inverter</span><span lang="EN-US">(NSI) is a recently developed dual output converter. It can be used to drive two three-phase loads independently. As a substitute to two separate conventional voltage source inverters, the NSI has been, already, proposed in various industrial applications to reduce the number</span><span lang="EN-US">of semiconductor switches and its associated energy losses and drive circuitry. On the other hand, the Direct Torque Control</span><span lang="EN-US">(DTC) is a robust control scheme of AC motors, which consist of selecting proper state vectors of a conventional voltage source inverter. The NSI, having a different working principle from the conventional voltage source inverter and taking into account the varying influence of active space vectors on motor’s torque and stator flux, a Direct Torque Control is suggested in this paper to, efficiently, drive two induction motors independently, while minimizing the torque and stator flux ripples of both motors. Simulations results confirm the effectiveness of the proposed algorithm. In addition, application of this newly proposed control scheme in operation of an Electric Vehicule</span><span lang="EN-US">(EV) is demonstrated.</span>

<p><span>This work presents a novel switching technique for five leg inverter in dual motor control. As the technology advances in industry, requirements in reducing the cost plays an important role with reliable product design. In conventional method, the six legs are used in 2- three phase Voltage Source Inverters (VSI) to control 2 motors. This proposed technique will give the improved performance of speed control for dual motor control using Five Leg Inverter (FLI). New proposed method suggests to use 5-inverter legs instead of 6-inverter legs to control 2 induction motors. New Switching technique proposed in FLI system is designed in effective way that improved performance and Total Harmonic Distortion of ~23% achieved. The load sharing on common leg is called Common Mode (CM) of operation. In this new method, closed loop control designed by using space vector pulse width modulation (SVPWM) and Direct Torque Control (DTC) in FLI Technology. With this new method smooth speed regulation is achieved when load torque is changed. THD% for CM-FLI is reduced when compared with convetional FLI technique. The new Switching technique is controlled in effective way that the common leg is not overloaded and able to drive both the induction motors independently at required speeds. Proposed switching technique verified at different operating speeds with No load and rated torque. Simulation results computed using MATLAB/SIMULINK Software. </span></p>

Traction Drives

The main requirements for traction electric drives are listed and discussed. The direct torque control of an induction motor electric drive is established by a survey of operation modes of traction electric drives to thoroughly satisfy the requirements for traction electric drive. The topologies and operation principles of two-and three-level voltage source inverters are presented. The advantages and shortcomings of three-level voltage source inverters to be applied on locomotive traction drives are highlighted in relation to the two-level ones. The recommendations of choice between different voltage source inverter topologies are given. The topology and principles of operation of direct torque control of induction motors with two- and three-level voltage source inverters are described. The simulation peculiarities of electric drives with direct torque control and two- and three-level inverters in Matlab are considered. The simulation results are presented. The techniques to reduce the torque oscillations are shown and implemented in Matlab Simulink.
