LED lighting has shifted from niche to mainstream in controlled environment agriculture, driven by improved spectrum, output, and cost reductions. Energy efficiency of LEDs allows growers to achieve ...

Abstract: In this paper, we propose three advanced digital predictive current-mode control (DPCC) algorithms based on a simplified estimation method of duty cycle ...

Abstract: Usually, PWM operation is selected to drive High Brightness LEDs, because the dimming behavior is more linear than in DC operation. Nevertheless, to obtain an enhanced operation of the ...
