Title: Supply circuit for variable speed asyn. motor - has three phase thyristor rectifier coupled through filter to inverter
IPC: H02P27/06
Filed: 1976-04-29
Abstract: The supply circuit, for a variable speed async. motor consists of 3-phase thyristor rectifier coupled by its input to the 3-phase supply and by its output via a filter to the 3-phase thyristor static inverter supplying the motor. A voltage/frequency converter is coupled to the output of the filter at the rectifier's output. The output of the V/f converter controls the circuit that determines the frequency of the output of the inverter. The advantage lies in the simple way in which the motor's speed (determined by inverter frequency) is made dependent on the action of the voltage regulator controlling the rectifier.
