  • Patent number: 10925137
    Abstract: Apparatuses, systems and methods for regulating the output currents of a power supply at a target output current include a buck converter module operably connected to a power source and a load. A first switch couples the power source to the buck converter module during a first period of a given operating cycle, while the buck converter module stores and provides electrical power to the load. During a second period, a second switch may discharge, the electrical power stored during the first period. A current sensor senses the currents during at least one of the first period and the second period and, over the operating cycle, the switching times are adjusted so the average output current equals the target output current. Adjustments to the first and second period durations result in maximum and a minimum currents symmetrically disposed about the average current provided to the load during the operating cycle.

  • Patent number: 10904984
    Abstract: Two-wire dimmer operation includes controlling conduction of power to a lighting load. In one aspect, based on a conduction angle adjustment, power supply voltage is monitored and a maximum conduction angle is established based thereon. In another aspect, a dimming level signal is received and a dimming level for a dimmer is set based on the received dimming level. The dimming level signal indicates a desired dimming level for a dimmer, and a maximum value for the dimming level signal is based on a dimmer power supply voltage. In yet another aspect, based on detecting an adjustment to increase a conduction angle of a dimmer, the conduction end angle is increased and the conduction start angle is also increased. This results in a net increase in the conduction angle for controlling operation of the dimmer.
