各位能否推荐1500W 电源方案
Input voltage: 90~264V
Out put: +50V and -50V
Output power: 1500W
或者700W, 用两路独立的电源

Hi
PFC可以采用UCC28070这类两相交错PFC控制芯片:http://www.ti.com.cn/product/cn/UCC28070?keyMatch=ucc28070&tisearch=Search-CN
然后再用全桥移相的控制芯片UCC28950/UCC3895转换得到+/-50V: http://www.ti.com.cn/product/cn/UCC28950/toolssoftware
多谢快速回复! 请问 UCC28180 + UCC28950 54V/30A TI DESIGN PMP6712 方案 (http://www.ti.com.cn/tool/cn/pmp6712#1), 是否可行?
UCC28180 与UCC28070 哪个合适些?
两组 UCC28180或 UCC28070 + UCC28950 独立电源似乎更好。
