20110221418 | POWER TRACKING DEVICE AND POWER TRACKING METHOD THEREOF - A power tracking device for a power generation apparatus is provided. A multiplier generates a power level signal according to a current signal and a voltage signal both sensed from the output of the power generation apparatus. A sample-and-hold circuit samples the power level signal according to a sampling clock and generates a current level signal, a peak level signal, and a threshold level signal according to an update signal. A compare circuit compares the current, peak and threshold level signals to generate the update signal and a change signal. A converter performs pulse width modulation (PWM) to generate a PWM signal according to a control signal corresponding to the change signal and converts the output of the power generation apparatus to a load according to the PWM signal. | 09-15-2011 |
20100141160 | TRACKING REGULATOR FOR LED LOAD AND POWER REGULATION METHOD THEREOF - A tracking regulator for a plurality of light emitting diode (LED) loads is provided. The tracking regulator includes a power supply and a control circuit coupled to the power supply. The power supply provides a power signal to each of the LED loads according to a control signal, wherein each of the LED loads provides an output signal according to the power signal. The control circuit detects the output signals from the LED loads to generate the control signal, so as to control the power supply to adjust the power signal. | 06-10-2010 |
