从来没玩过这东西,搜了半天还是没什么头绪,多谢啦。 | g******u 发帖数: 3060 | 2 you need other factors, such as power factor, topology, etc.
What do you mean by "programmable"?
If you don't have much experience on transformers, you can rectify 24VAC and
filter it then feed it to a DCDC, then it's super tiny and simple. Only if
your requirement on power factor is low. |
