the conduction angle modulation interval is from 0.91 π to π. Based on the practical testing results
the design can realize dimming control
the total harmonic distortion rate is less than 5%
the voltage flicker amplitude is less than 4%
and the power factor is greater than 0.90. This design has a wide application prospect in the field of intelligent lighting.
