TMS320F28069: 使用28069以及SFRA进行BOOST电路系统优化的若干问题

Part Number: TMS320F28069
Other Parts Discussed in Thread: POWERSUITE, SFRA

请教一下各位大师,现在我正在做一款以28069为核心的异步boost电路,软件用官网powerSUITE 2 Phase Interleaved PFC Kit做的移植,现在遇到的问题是BUILD1,2,3电流环,电压环都能形成闭环,但是输出电压随负载变化的动态响应不好,想用SFRA来优化系统,GUI能连接上,但是扫描完后,总是只有相频图,幅频图扫描不到数据,而且相频图曲线也不对,请大家帮忙分析一下,非常感谢!
