ence using dsp instead of analog? i'm starting a project but still debating
pros and cons..

发帖数: 3060 | 2 in my commercial vehicle application, microcontroller controlled opto
feedback+ secondary rectification is good and accurate enough. of course I
think in sth like Agilent power supplies, they must use more accurate
methods, another dream company. ( i don't know how can they make 0.1% line
and load regulation)
anyway, I think if you use simple methods, you can design everything of the
power converter yourself, but if you would use sth like DSP, you must have a
small group there. |

TI has some nice evaluation kit for digital control LLC. and it can be a good starting point

these are not in the same power range bah.. can not compare. |

你用analog做dqo转换是不是太费劲了？
如果只是普通的DCDC converter 或者单相的AC/DC converter. 很多现成的analog
solution。
用DSP也太牛刀了。而且，Fsw也作不上去。

但是通讯电源现在用DSP已经比analog划算了
