摘要
LLC谐振变换器具有效率高、工作频率高、结构简单、功率密度高等优点,而得到广泛应用。针对服务器电源的要求,采用交错并联PFC+Standby Buck+交错并联LLC的功率架构,解决了LLC谐振变换器在应用中的软起动和短路限流的问题,大大减小输出电容的电流纹波,同时保证系统达到铂金版的效率要求。
LLC resonant converter has a lot of merits such as high efficiency, high switching t}equency, simple structure and high power density. So a novel power architecture for telecom and server power which consists of Interleaved PFC, Standby Buck and Interleaved LLC was proposed. This system can solve the issue of soft start and current limit in practical application of LLC, reduce the tipple of output capacitor, and also satisfy the platinum efficiency requirement of CSCI.
