摘　　要：为进一步提高能源利用率,实现无需储能设备的目的,以STM32单片机为控制核心,设计一种基于双Buck输入变换器原理的太阳能与市电智能互补供电系统,并且利用此供电系统经过RT8480驱动芯片给LED光催化器直接供电。通过实验验证,LED光催化器可稳定工作在太阳能单独供电、市电单独供电、太阳能与市电联合供电的三种供电系统模式下。此系统大大提高了能源利用率,同时,也免去了蓄电池带来的成本及对环境的污染,实现节能环保的目的。In order to further improve energy efficiency and achieve the purpose of avoiding energy storage equipment, STM32 single-chip microcomputer was used as the control core. A solar energy and main intelligent complementary power supply system based on double Buck input converter principle as designed, and the power supply system was directly used to the LED photocatalyst by RT8480 the driver chip supplies power. Through experiments, the LED photocatalyst could work stably in the three power supply system modes of solar energy alone, main power supply alone, and solar power and mains supply. The energy utilization rate was greatly improved, and at the same time, also the cost brought by the battery and the pollution to the environment was eliminated. The purpose of energy saving and environmental protection was achieved.
