Circuit arrangement and method for control of an electric motor, in particular of a washing machine

摘要

The configuration has a driver circuit (200) connected to a voltage intermediate circuit and power switches. A control unit is connected to the driver circuit to generate control signals for controlling rotation speed of a motor. The driver circuit generates short-circuit control signals as a function of a detection of an overvoltage of a voltage intermediate circuit over a desired voltage range for driving the power switches. An independent claim is also included for a method for controlling an electric motor having motor terminals.
