  • Drive control system for a multiphase motor powered by a power converter
    Patent number: 6788014
    Abstract: A drive control system for a multiphase motor powered by a power converter of a type including a multi-pulsed bridge circuit with a plurality of controllable converter valves and a same number of electrically isolating devices, includes a control unit, with the input side of the converter valves connected to the output side of the control unit via the electrically isolating devices, and an armature short-circuit braking device for connection to the input side of electrically isolating devices of one bridge side of the bridge circuit. An overvoltage recognition device is provided to receive a signal commensurate with a limit value, and a signal commensurate with a determined actual input voltage of the power converter. A trigger circuit is connected to the armature short-circuit braking device, and has an input connected to an output of the overvoltage recognition device and supplied with a signal for the armature short-circuit braking device.
