  • Motor driving system and method for starting a motor
    Patent number: 7965052
    Abstract: A method and system is provided for starting a motor which is useful, among other things, is useful for motors under unknown or variable load/inertia conditions. If a first attempt to start the motor using a first frequency ramp-up rate fails, a subsequent start attempt may be performed at a decreased frequency ramp-up rate. Iteration may be performed until starting of the motor is successfully achieved.

  • Power factor correction and driver circuits
    Patent number: 7952293
    Abstract: Power factor correction and driver circuits and stages are described. More particularly, power factor correction circuits are described that utilize an auxiliary inductor winding for power regulation. Driver circuits configured for electrical loads such as series arrangements of light emitting diodes are also described. An exemplary embodiment of a driver circuit can implement a comparator and/or a voltage regulator to allow for improved output current uniformity for high-voltage applications and loads, such as series configurations of LEDs. Embodiments of PFC stages and driver stages can be combined for use as a power supply, and may be configured on a common circuit board. Power factor correction and driver circuits can be combined with one or more lighting elements as a lighting apparatus.
