    摘要: The present invention relates to a Light Emitting Diode (LED) selection circuit for an LED driver that drives multiple unequal lengths of LED strings, which selectively turns the LED strings ON and OFF corresponding to an input alternating current (AC) line voltage. The LED driver provides optimal efficiency as input AC line voltage varies from low to high voltages (i.e. 90V to 150V for nominal 120 VAC operation and 190V to 250V for nominal 220 VAC operation). Thus The LED driver can be used internationally since it accepts voltages from virtually every industrialized country in the world. The LED selection circuit in accordance with the present invention comprises a rectifier, multiple LED strings, multiple current sources and a controller. The controller generates multiple signals to the corresponding current source and turns ON and OFF the LED strings.

    摘要: The present invention relates to a pulse-width modulation (PWM) control device, especially to a PWM control device for use with a TRIode for an Alternating Current (TRIAC) dimmer. The PWM control device is comprised of a load, a rectifier, a PWM control module and a PWM controllable ballast. The load may be a gas discharge lamp, a motor, a heating device or a light emitting diode lamp. The rectifier is connected to a power module and rectifies a truncated sinusoidal voltage from the power module to a pulsating truncated direct current (DC) voltage. The PWM control module is connected to the power module and the rectifier and generates a PWM control signal. The PWM controllable ballast is driven by a boost circuit and is controlled by the PWM control signal that limits current to a proper value for the load.

    摘要: An approach is provided for a power factor compensating method to compensate other electronic devices that use a common power source in order to improve power factor from the perspective of a power company. The other electronic device is a type of a non-linear load, and the method enables a compensator to receive a supply voltage from the power source commonly connected to the traditional electronic devices and disables a load of the compensator for a period. The period corresponds to a range that makes an overall supply current more proportional to the supply voltage.
