  • Switching frequency variation for a motor
    Patent number: 12474682
    Abstract: A controller circuit is configured to generate, using a random number generator, a set of bits and determine a switching frequency using the set of bits. The controller circuit is further configured to control a switching circuit to switch at the switching frequency to drive a motor.
    Type: Grant

    Assignee: Infineon Technologies AG
    Inventors: Stefan Golisch, Sandro Purfürst
  • Adapted switching signal for a motor
    Patent number: 12040728
    Abstract: A circuit is configured to generate a first switching signal and a second switching signal. During a first portion of a first switching period, both the first switching signal and the second switching signal indicate to turn-on and turn-off. During a second portion of the first switching period, the first switching signal indicates to turn-on and the second switching signal indicates to turn-off. In response to a determination that a measurement time threshold exceeds the first switching period, the circuit is configured to generate a first adapted switching signal that extends the turn-on portion by a time value in the first switching period and to generate a second adapted switching signal that extends the turn-on time by the time value in a second switching period. The circuit is further configured to control switching circuitry using the first adapted switching signal and the second adapted switching signal to operate a motor.
