Directly powered by a AC voltage, for a soft switching method, the proposed circuit can implement a higher efficiency and power factor (PF) as well as a lower total harmonic distortion (THD) [1] and avoid some thorny problem such as EMI and EMC noise during hard commutations with an adaptive load network. By utilizing the converter-free technique, the work can be fabricated into a BCDMOS process technology without using any inductors and capacitors. The proposed circuit is designed and simulated under BCDMOS technology. The maximum output current for LED can achieve 1A under 1KHz 110V/AC (1 KHz 220V/AC) condition.
