Optimal Control of Transistor SRM Converters with Reduced Number of Switching Element

摘要

Nowadays switched reluctance motor (SRM)uddrives have been widely used in the field of controlledudelectric motor drives. The paper proposes a simple controludmethod for SRM drives. Current control of the reducedudswitching item number SRMuddrives contain modifiedudcurrent reference signal. This method provides that torqueudripple would not be significantly higher at a Miller-kindud(n+1) transistor converter controlled n-phase drive - inudother words a reduced switching item number SRMudconverter feed - than at independent current control in eachudphases carried out with 2n transistors.
