METHOD FOR CONTROLLING, CONTROL CIRCUIT, BRAKE SYSTEM AND USE

WIPO Patent Application WO/2019/138006

A1

The invention relates to a method for controlling a multi-phase motor by means of a control circuit, in which the control circuit comprises a plurality of transistors, and a first path and a second path are provided for each phase of the motor, at least one transistor being respectively associated with the first and the second path of the different phases, and a normal mode (N), a first control mode (A1) and a third control mode (A3) are provided, all of the transistors of the second path being short-circuited for the first control mode (A1) and all of the transistors being opened for the third control mode (A3), a second control mode (A2) being provided in which an alternate operation between the first control mode (A1) and the third control mode (A3) takes place, the following steps being carried out: detecting an undervoltage (U1, U2, U3) or an overvoltage (UES) in the control circuit; operating the control circuit in the first control mode (A1) when a first undervoltage (U1) has been detected, and operating the control circuit in the second control mode (A2) when a second undervoltage (U2) has been detected. The invention also relates to a control circuit for controlling the motor, to a brake system comprising such a control circuit, and to the use of the control circuit in a brake system.
