　　TI公司的TIDA-00951是2kW 48V-400V效率大于93%的绝缘双向DC/DC转换器参考设计,数字控制,工作范围从36V-60V电池和300-400V DC总线,内置DC总线过流和过压以及电池过流等保护.隔离的CAN,I2C和蔼RS-485通信接口,主要用在服务器PSU和通信整流器,不间断电源(UPS),工业电源,电池充电器和能量存储系统.本文介绍了UPS系统架构图,2kW UPS参考设计TIDA-00951主要特性和指标,框图,电路图,材料清单和PCB设计图.

　　The TIDA-00951 design provides a reference solutionfor a 2-kW isolated bidirectional DC-DC convertercapable of power transfer between a 400-V DC busand a 12- to 14-cell Lithium battery pack for use inUPS, battery backup and power storage applications.

　　This TI Design works as a >93% efficient, current fed,active clamped boost converter with ZVS in thebackup mode and voltage fed full-bridge batter chargerwith >93% efficiency in the charging mode. This TIDesign has built-in protection for DC bus overcurrentand overvoltage and battery overcurrent.

　　2kW UPS参考设计TIDA-00951主要特性:

　　• Digitally Controlled Isolated Bidirectional DC-DCConverter

　　• Operates as Active Clamped Full Bridge BoostConverter With ZVS For All Low-Voltage Switchesat High Loads

　　• Operates as Active Clamped Voltage Fed BuckConverter With Synchronous Rectification toImprove Efficiency When Charging Battery

　　• Wide Operating Range From 36- to 60-V Batteryand 300- to 400-V DC Bus

　　• Cost Optimized Design Using 100-V FET on Low-Voltage Side, Eliminates Requirement forParalleling Multiple FETs up to 2 kW
