Electric Motor Drive with Inverter Output Filter

The paper focuses on some aspects of control and estimation in electric drives with inverter output filters. The filters are used in some industrial drives with pulse width modulated (PWM) inverters. They smoothes the motor supply voltage and current so nearly sinusoidal shapes are obtained. The filters can also limit the bearing current and shaft voltages. Because of the voltage drop and phase...

Cascaded Multilevel Inverter for Induction Motor Drive

In this paper presents a symmetrical five level cascaded inverter topology for Induction motor drive. It can continuously works at lower power stage. For this symmetrical circuit, when the number of level is increased, the voltage and power will also get increased. For reducing harmonics the Sinusoidal PWM method is used. The multilevel inverter gives the output to drive the three phase Inducti...

A Novel Concept for Multimachine Drive System with Single Inverter Supply

The interest in multiphase machines for high performance applications has been growing in recent years due to their potential advantages over three-phase machines. One of the possibilities of taking advantage of the additional degrees of freedom that exist in multiphase machines is the series connection of several multiphase machines, with the supply coming from a single multiphase inverter. Th...

A Current-Source-Inverter-Fed Induction Motor Drive System with Reduced Losses

Standard lowand medium-power induction motor drives are based on the pulsewidth modulation (PWM) voltagesource inverter fed from a diode rectifier. The dual topology, based on the current-source inverter/rectifier structure is used in mediumand high-power applications. This paper analyzes the existing motor drives based on current-source topologies and proposes a control strategy that addresses...
