Patent number: 11764688Abstract: A load control device for controlling the amount of power delivered to an electrical load (e.g., an LED light source) includes first and second semiconductor switches, a transformer, a capacitor, a controller, and a current sense circuit operable to receive a sense voltage representative of a primary current conducted through a primary winding of the transformer. The primary winding is coupled in series with a semiconductor switch, while a secondary winding is adapted to be operatively coupled to the load. The capacitor is electrically coupled between the junction of the first and second semiconductor switches and the primary winding. The current sense circuit receives a sense voltage and averages the sense voltage when the first semiconductor switch is conductive, so as to generate a load current control signal that is representative of a real component of a load current conducted through the load.Type: GrantFiled: May 2, 2022Date of Patent: September 19, 2023Assignee: Lutron Technology Company LLCInventor: Dragan Veskovic

Patent number: 11751307Abstract: A device comprises a voltage regulator, circuits, a voltage-to-current converter, a control bus, a resistor and a resistor network. Each of the circuits has at least one LED connector and one LED driver. Each of the circuits has a measuring circuit for detecting voltage differences between the potentials of LED terminals and a reference potential. Further, each of the circuits includes a local controller. The local controller withdraws a current from the control bus in dependence on the detected voltage differences. Bias current sources inject bias currents into the control bus in form of a sum current of the injected bias currents. The resistor performs a current-to-voltage conversion of the sum current to a control voltage. The voltage-to-current converter converts the control voltage into a current. The resistor network converts the current into a voltage value. An output voltage of the voltage regulator depends on the voltage value.Type: GrantFiled: May 20, 2020Date of Patent: September 5, 2023Assignee: Elmos Semiconductor SEInventors: Carsten Leitner, Andre' Krieger, Christian Schmitz, Thomas Geistert
