  • Patent number: 11932979
    Abstract: A laundry treating appliance for treating laundry items according to an automatic cycle of operation can include a cabinet defining an interior and having an access opening providing access to the interior. A tub can be located within the interior and can at least partially define a liquid chamber. A drum is rotatably mounted within the liquid chamber and at least partially defines a treating chamber.

  • Patent number: 10958198
    Abstract: A system includes an electric motor, at least one pair of high side and low side switches connected to the electric motor, and a microcontroller connected to the high side and low side switches. At least the low side switches have a minimum on-time requirement. The microcontroller controls the switches by outputting a pulse-width modulation (PWM) signal. At least the PWM signal outputted to the low side switch is center-aligned to the off-time. When a request is made to the microcontroller resulting in a low side on-time of zero with a previous duty cycle request that is greater than a predetermined threshold, the microcontroller is constructed and arranged to extend the duty cycle of the low side switch of the at least one pair of switches into the next period to a duration of the required minimum on-time.
