Abstract
This paper studies the problem of power factor control strategy in semiconductor lighting systems. Firstly, the development process and basic principle of the semiconductor lighting system are analyzed, and the concept and significance of power factor are introduced. Then, three main control strategies to improve power factor for semiconductor lighting systems are proposed, which include power factor control strategy based on AC capacitors and inductors, power factor control strategy based on improving THD, and power factor control strategy based on digital control. The simulation analysis is carried out using PSIM and the hardware implementation is validated by experiments. The results show that the power factor control strategy for semiconductor lighting systems can effectively reduce the numerical value of power factor, while improving the stability and efficiency of the system. The research in this paper has important significance and practical value for improving power factor and energy conservation in semiconductor lighting systems.
