[原创] TI TIDA－01407 400W 48V汽车电源参考设计

TI公司的TIDA-01407是用于汽车的36V-60V输入12V输出的400W汽车电源参考设计,采用增强的相移全桥控制器实现可编延时,从而保证了各种工作条件下零电压开关(ZVS).输出采用同步整流,具有快速瞬态响应和高回路带宽.无负载待机功耗< 100-mW,主要用在HEV/EV牵引逆变器,干双离合变速箱传输,电子控制单元和HEV/EV DC/DC转换器.本文介绍了参考设计TIDA-01407主要特性,电池驱动逆变器系统框图以及参考设计TIDA-01407主要系统指标,框图,电路图,材料清单和PCB设计图.

This reference design is an automotive, 400-W, phaseshiftedfull-bridge converter which enables a 36-V to60-V DC input and 12-V output. The enhanced phaseshiftedfull-bridge controller implements programmabledelays which ensure zero voltage switching (ZVS) overa wide range of operating conditions. The outputimplements synchronous rectification, which enablesfast transient response and a high loop bandwidth.

The system regulates 12 V at no load with less than100 mW of standby power. Pseudo isolation isachieved through a transformer to prevent the 48-Vbattery from being shorted to the secondary side. Thehalf-bridge gate drivers can withstand a maximum bootvoltage of 120-V DC.

参考设计TIDA-01407主要特性:

• Phase-Shifted Full-Bridge Converter Over InputVoltage of 36-V to 60-V DC; Output Power up to400 W..
