Research on a Smart LED Lighting Based on Improved Flyback Driver

Aiming at various lighting energy supply circuits currently used, a improved Flyback circuit is proposed applied in the smart LED lighting in this paper, which can realize photovoltaic power generation and energy storage, and stored energy is inverter to the grid or AC load. The proposed driver can realize multi-form and multi-function utilization of energy. The circuit operating process is analyzed and the key parameters relation equations are set up in detail. The design circuit uses 18V photovoltaic panel as input, 24V 6AH lead-acid battery as storage part, three 1W 350mA LED lamps in series as LED lamp group, and 50 ohms AC load as DC-AC inverter load. The simulation software PSIM is carried out to verify the feasibility of the improved circuit design and analysis.
