stator resistance estimation in direct vector control for high performance torque controlled induction motor drives
sensorless speed torque control of induction machines has been widely used in many industrial applications. the simple method of direct vector control can provide tacholess control as well as more complex approaches. in this method, the motor flux can be obtained by measuring voltage and current and integrating motor back electromotive force. the only required motor parameter is stator resistan...
متن کاملHybrid SHM-SHE Modulation Technique for a Four-Leg NPC Inverter With DC Capacitor Self-Voltage Balancing
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—In this paper, SHM (Selective Harmonic Mitigation) and SHE (Selective Harmonic Elimination) modulation techniques have been combined to produce appropriate pulses for four-leg three-level NPC (Neutral Point Clamped) inverter. In...
متن کاملSelected Problems of Induction Motor Drives with Voltage Inverter and Inverter Output Filters
. Fast switching of power devices in an inverter causes high dv/dt at the rising and falling edges of the inverter output waveform. . High dv/dt in modern inverters is the source of numerous disadvantageous effects i.e. faster motor bearings degradation, over-voltages on motor terminals, failure or degradation of the motor winding insulation due to partial discharges, increase of motor losses, ...

متن کاملMultilevel Inverter Fed Induction Motor Drives
Induction motor drive is used in almost all industries including oil and gas sectors, production plants and process industries. Speed control of induction motor is a major concern. The proposed technology implements a better speed control for induction motor drives using a multilevel inverter. The switching sequences are generated by optimized pre-calculated angles for controlling induction mot...
