SWITCHED RELUCTANCE MOTOR WITH A DRIVER CIRCUIT AND METHOD FOR OPERATING A SWITCHED RELUCTANCE MOTOR

摘要

The present invention relates to one kind to be used for run switch reluctance motor( 4 ),In particular for the driving device of motor vehicle,Wherein supply voltage( UDC )It draws from DC voltage source( 8 ),Wherein during the charging process,Phase winding( 20a,20b,20c )Magnetic resistance motor( 4 )The energy of supply voltage charges,During discharge,By energy from phase winding( 20a,20b,20c )Electric discharge is transmitted to the first energy stores( 26,64 ),Wherein in a up-conversion process,Supply voltage( UDC )It is up-converted to a voltage( UDC ' )Be stored in the second energy accumulator( 26,62 ),Wherein in pressurization,Phase winding( 20a,20b,20c )Supply,With energy storage energy accumulator,The beginning of conversion process is wherein gone up according to the rotation speed of magnetic resistance motor( 4 ).
