Research on LED Driver Power Based on LLC Resonant Converter

随着对LED工作稳定性的要求提高,驱动电源的性能要求也在不断提高。LLC谐振变换器实现的软开关技术降低了开关损耗、提高了功率密度,使得其在对系统可靠性要求较高的领域有着广泛应用。通过对国内外文献的研究,总结目前驱动电源的发展现状,并分析了未来驱动电源的发展趋势。

As the requirements for LED operational stability increase, the performance requirements of the drive power supply are also increasing. The technology of soft switching is realized by the LLC resonant converter which reduces switching losses and increases power density, making it widely used in fields of requiring high system reliability. This paper summarizes the current development situations of driving power supply through the research of domestic and foreign literatures, and analyzes the development trend of driving power in the future.
