  • Patent number: 11924939
    Abstract: A power converter circuit may include a control circuit configured to generate a drive signal for rendering a semiconductor switch conductive and non-conductive to generate a bus voltage across a bus capacitor. The control circuit may adjust a minimum operating period of the drive signal to a first value when an output power of the power converter circuit is greater than a first threshold and to a second value when the output power is less than a second threshold. The control circuit may comprise a comparator that generates the drive signal in response to a sense voltage and a threshold voltage. When operating in a standby mode, the control circuit may adjust a magnitude of the threshold voltage based on an instantaneous magnitude of an alternating-current line voltage received by the power converter circuit, such that an input current drawn by the power converter circuit is sinusoidal.

  • Publication number: 20230389144
    Abstract: A multiple location load control system may comprise a main load control device and an accessory load control device. The main load control device may control an amount of power delivered to an electrical load from an AC power source using a control circuit and a controllably conductive device. The accessory load control device may be coupled to the main load control device via an accessory terminal. The accessory load control device may detect a user input for changing a characteristic of the electrical load and may send a signal to the main load control device indicating the user input. The main load control device may detect a pattern of the signal based on a threshold and further determine the user input in response to the detected pattern. The main load control device may adjust the threshold based on line/load conditions of the multiple location load control system.

  • Publication number: 20230232515
    Abstract: A load control device coupled between an AC power source and an electrical load may operate in a three-wire mode or a two-wire mode based on whether the load control device is connected to a neutral side of the AC power source. The load control device may further comprise first and second zero-cross detect circuits to be respectively used in the two-wire mode or the three-wire mode, and a neutral wire detect circuit configured to generate a neutral-wire detect signal indicating whether the load control device is connected to the neutral side of the AC power source. A control circuit of the load control device may determine whether the load control device should operate in the two-wire mode or in the three-wire mode in response to the neutral-wire detect signal.

  • Publication number: 20230133984
    Abstract: A control device configured for use in a load control system to control an electrical load external to the control device may comprise an actuation member having a front surface defining a capacitive touch surface configured to detect a touch actuation along at least a portion of the front surface. The control device includes a main printed circuit board (PCB) comprising a control circuit, a tactile switch, a controllably conductive device, and a drive circuit operatively coupled to a control input of the controllably conductive device for rendering the controllably conductive device conductive or non-conductive to control the amount of power delivered to the electrical load. The control device also includes a capacitive touch PCB that comprises a touch sensitive circuit comprising one or more receiving capacitive touch pads located on the capacitive touch PCB and arranged in a linear array adjacent to the capacitive touch surface.
