摘要
通信基础设施的设备使用多种电源系统部件。例如在前端馈电网有负载均流和(N+1)冗余的功率因数校正(PFC)AC/DC电源;在后端有高效率DC/DC变换器模块和负载端变换器。本文评论了若干通信电源设计的要求,考虑其成本、性能和标准,还讨论了许多新的分布式电源结构和最适用的变换器拓扑及PWM控制器。
Communications infrastructure equipment employs a variety of power system components. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense,high efficiency DC/DC modules and point-of-load converters on the back-end. In this article we review several challenging telecommunication power supply designs and discuss a variety of new power distribution architectures and converter topologies and PWM controllers best suited considering cost, performance and schedule criteria.
