原标题:TI TIDA-00951 2kW UPS电源双向DC变换参考设计
TI公司的TIDA-00951是2kW UPS电源双向DC/DC转换器参考设计,工作电压从36 到 60V电池组和300到400-V DC总线,效率大于93%,通信接口包括CAN,I2C和RS-485,主要用在服务器PSU和电信整流器,不间断电源(UPS),工业电源,电池充电器和能量存储系统.本文介绍了参考设计TIDA-00951主要特性和指标,框图,典型UPS系统架构图以及参考设计TIDA-00951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.
参考设计TIDA-00951主要特性:
• Digitally Controlled Isolated Bidirectional DC-DCConverter
• Operates as Active Clamped Full Bridge Boost
Converter 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
• Built-in Cold Start Procedure and Fast ModeTransfer (< 100 μS) From Battery Charger toBackup Power Supply
