Anatoly Shteynberg,Dongsheng Zhou,Harry Rodriguez,Mark Eason,Bradley M. Lehman,Stephen F. Dreyer,Thomas J. Riordan +6 more
TL;DR: In this article, an apparatus, method, and system for providing AC line power to lighting devices such as light emitting diodes (LEDs) is described, which consists of a plurality of LEDs coupled in series to form an array of segments of LEDs.
Patent
Digital Driver Apparatus, Method and System for Solid State Lighting
TL;DR: In this article, a switch for switching electrical current through the LEDs, a current sensor, a first comparator adapted to determine when a switch electrical current has reached a first predetermined threshold, and a second comparator adaptively determined when the switch electrical currents reached a predetermined average current level; and a controller is adapted to turn the switch into an on state and an off state.
Patent
Power converter controller having event generator for detection of events and generation of digital error
TL;DR: In this paper, an event detection module detects various events of a power converter in real time at the switching frequency of a switch in the power converter according to predetermined criteria, and a pulse generator generates control signals for controlling the on-times and off-times of the switch based on the various detected events.
Patent
Digital Compensation For Cable Drop In A Primary Side Control Power Supply Controller
TL;DR: In this article, the primary side sensing is used to regulate the output voltage at a cable end without any remote sensing of cable connections back from the load, which is accomplished by approximating the current from the control voltage in the control loop through the relationship that defines the Ton time in terms of the Vc. Once the approximation of the output current is known, it is multiplied by a known fixed cable resistance.
Patent
Digital regulation of power converters using primary-only feedback
TL;DR: In this paper, the authors propose a digital control circuitry for sensing an output voltage feedback signal, comparing the sensed feedback signal to a reference at a determined time during a cycling of the switch, and regulating the output voltage by either enabling or inhibiting cycling of a switch by a cycle of a drive signal produced by pulse generation circuitry in response to the comparison.
