The typical LED lighting applications in the 25W-100W power range are street lighting (residential roads) and public places like parking lots. Power conversion efficiency, cost-effective implementation of PFC functions, and high color quality are now the three most important technical challenges. For example, in commercial lighting and street lighting applications, longer service life and the resulting lower maintenance costs are helping to overcome entry barriers with higher initial costs. LED lighting applications ranging from 25W to 100W have power factor requirements, so it is necessary to add power factor correction circuits.
This circuit can adopt a traditional two-stage structure, which includes an active discontinuous mode power factor correction (PFC) circuit and a DC-DC PWM conversion circuit. For example, Ansemy’s power factor correction controller NCP1607 has a very simple peripheral circuit and can provide good performance, “Zheng Zongqian said, For high-efficiency, low-cost, and small-sized LED solutions, it is worth recommending a single stage PFC circuit, which can achieve both power factor and isolated low-voltage DC output, and has significant cost advantages, making it a mainstream solution for medium power LED lighting. Ansemy Semiconductor’s NCP1652 provides the optimal control solution for achieving single stage PFC circuits
