  • Power converter for delaying entering burst mode and method thereof
    Patent number: 11398767
    Abstract: Various embodiments relate to a power converter including a resonant converter with an controller, the controller configured to control the converter to operate in a normal mode when output power is above a burst mode threshold level, start a timer when the output power falls below the burst mode threshold level, continue operating in the normal mode until the timer reaches a predetermined time and operate in burst mode when the timer reaches the predetermined time.
    Type: Grant

  • End of lamp life protection circuit with bi-level detections for the electronic ballast and method thereof
    Patent number: 8378592
    Abstract: The configurations of an end of lamp life protection circuit for a ballast and a method thereof are provided in the present invention. The proposed circuit includes a voltage-dividing circuit receiving an input voltage and outputting a first and a second divided voltages and a switch apparatus raising the first divided voltage when the second divided voltage is less than a first pre-determined threshold value and turning off the ballast when the first divided voltage is higher than a second pre-determined threshold value.
