    A novel high efficiency multi-channel LED using a soft self-commutating technique and load adaptive method is presented in this paper. Directly powered by a AC voltage, for a soft switching method, the proposed circuit can implement a higher efficiency as well as a lower total harmonic distortion (THD) and avoid some thorny problem such as EMI and EMC noise during hard commutations with self-commutating structure and adaptive load network. By utilizing the converter-free technique, this work can be fabricated into a BCDMOS process technology without using any inductors and capacitors. The proposed circuit is designed and simulated based on PSpice Model. The maximum output current and the efficiency for LED achieve 1.28A and 89.1% under 1KHz 220V/AC condition.
