A Single-stage LED Driver for The Street Lighting System

A single-stage LED driver for the street lighting is proposed. The system consists of a constant current circuit and a constant voltage circuit, and the constant voltage circuit is gotten by integrating a buck-boost circuit and a flyback circuit.The peak current control mode is adopted in the constant current circuit which is a boost circuit and works in PWM mode. The theoretical analysis and design procedures of the proposed lighting system are proposed and discussed in detail in the paper. Streszczenie.
