The sensorless model predictive force control (SMPFC) is a strong method for controlling the drives of three-phase 4(6)-switch inverter linear induction motors. This kind of inverter can be employed for fault tolerant control in order to solve the problem of open/short circuit in 6-switch inverters (B6). This paper proposed a method for the SMPFC of a linear induction motor (LIM) with a 4-switc...

The objective of the paper is to develop a microcontroller controlled four switch three phase inverter (FSTPI) to drive three phase induction motor with minimum hardware. This inverter uses four switches instead of conventional six switches, it has lesser switching losses, lower electromagnetic interference (EMI), less complexity of control algorithms, robust control and reduced circuit complex...

Inverters with reduced number of switches have been proposed in the literature to improve the capability of cost reduction, total inverters size and switching losses of dc/ac inverter topologies. In addition, they have a lower probability of damaging the semi-conductor switches as well as lower commonmode currents. This paper proposes new designs for inverters with reduced number of switches. F...

In the viewpoint of reliability implication and cost effectiveness of three phase inverter, there should be less device count in inverter topology and fewer losses in the semiconductor switches. The earlier reported less device count topology by many research groups are facing the problem of Total Harmonic Distortion (THD). The imperfect design value of DC link capacitor is the main reason of H...

In this paper a new switching technique for Direct Torque Control (DTC) fault tolerant induction motor drive is presented, if one inverter leg is completely lost due to such abnormal condition, this system modifies the switching table of DTC system using the available stator voltage vectors in two phase mode with Four Switch Three Phase Inverter (FSTPI) topology to track the stator flux referen...

Received Jan 3, 2017 Revised Mar 3, 2017 Accepted Mar 17, 2017 In this paper a novel 5 switch seven level DC-AC inverter is being proposed. The proposed multilevel inverter uses reduced number of switches as compared to the switches used in the conventional multilevel inverter. The inverter has been designed to generate a 7 level AC output using 5 switches. The voltage stress on each of the swi...

This paper aims to provide a high performance sensorless control based on an Extended Kalman Filter (EKF) applied to fault-tolerant PMSM drive system with statorresistance estimation. It proposes a fast method of fault switches detection in the power converters. The considered drive is composed of three phases PMSM and a four leg three phase’s inverter when the fourth is the redundant leg. Afte...
