摘要
A low THD lighting system is disclosed. The lighting system includes a first lighting module and a second lighting module connected parallel to the first lighting module. During each AC cycle the first lighting module conducts current for a first portion of the cycle and the second lighting module conducts current for a second portion of the cycle. When combined, the total current drawn from the power source substantially tracks the shape of the applied AC voltage. Accordingly, there is minimal distortion, and low total harmonic distortion level is achieved.
