The article implements multichannel input LED drive circuit design with the wind,solar energy,electricity based on single-chip Intelligent Control. The wind and solar complementary power generation system can realize maximum power point tracking( MPPT) controlling strategies under different working conditions. The characteristics of wind and solar power generation are displayed using simulated wind-solar energy. The protection measures of wind-solar hybrid controller are improved. The battery charging controlling solutions optimizes the charging process stage by stage to realize the maximum utilization of energy with the intelligent control,thus achieving the best overall performance of drive circuit design.
