  • Apparatus having a flexible LED display module and a method of employing same
    Patent number: 11062628
    Abstract: A Light-Emitting Diode (LED) apparatus has one or more LED display modules. At least one of the one or more LED display modules has a plurality of LED display submodules. The plurality of LED display submodules are flexibly coupled to each other to form a flexible display surface.
    Type: Grant

  • Bridgeless single-stage AC/DC converter
    Patent number: 10879813
    Abstract: A single-stage AC/DC converter includes a boost PFC AC/DC converter and a half-bridge split-capacitor DC/DC converter. The boost PFC AC/DC converter includes a boost inductor, and the half-bridge split-capacitor DC/DC converter includes an inductor in series with a primary winding of a transformer. A method of operation of a single-stage AC/DC converter that includes a boost PFC AC/DC converter and a half-bridge split-capacitor DC/DC converter includes modulating a switching frequency of at least one switch. The method may further include maintaining a constant duty cycle, for example a duty cycle of 0.5. An implementation of the boost inductor in a boost PFC AC/DC converter of a single-stage AC/DC converter includes a variable boost inductor, such as two inductors of approximately equal inductance, and a boost inductor switching circuit, such as two single-pole, double-throw relays.
