| Abstract: | In order to increase the efficiency of conventional light-emitting diode(LED) driver,a Twin-Bus based LED driver configuration is proposed.Furthermore,a Twin-Bus type buck converter is presented for controlling the n-string LEDs to be dimming from true zero to the rated current level.Based on the proposed Twin-Bus configuration and Twin-Bus Buck converter,voltage stress of the low side n-switches is the difference between the Twin-Bus voltage sources.The operation principle and control scheme were described... |
