请问是否有一种首选的方法/工具来应用设计参数来制作实际的反激变压器？

你好汤姆，
您可能想要试用在线工具智能变压器选择器：
http://www.we-online.com/sts/
通过最小的输入，如输入/输出电压和电流，开关频率......您可以访问可能适用于您的应用的已设计的变压器。这是一个例子：
如果您找到适合您应用的变压器，您可以在此处订购：

Hi Tom,
You may want to try out the online tool Smart Transformer Selector:
http://www.we-online.com/sts/
With minimal inputs, like input / output voltages and currents , switching frequency ... you could get access to an already design transformer that may work in your application. Here is one example:
If you find a transformer that could fit in your application, you can order here:

Hope it helps.

嗨埃米尔：
我已经在Wurth有一个帐户，但没有意识到他们有一个设计工具。我尝试过但不幸的是我无法使用“现成的”产品。我考虑让他们做自定义设计，但由于这主要是个人项目，我不想使用他们的资源。我希望即使没有确切的可用工具，该工具也会给出建议。
谢谢，我真的很感激你的建议！

Hi Emil:
I already had an account with Wurth but did not realize they had a design tool.  I tried it but unfortunately I could not use an 'off the shelf' product.  I considered having them do a custom design but since this is mostly a personal project I did not want to use their resources.  I wish the tool would give suggestions even if nothing exact is available.
Thank You, I really appreciate your suggestion!

你好汤姆，
欢迎你。
三种输出应用并不常见，确实没有多少变压器设计可供选择。但是如果你可以分享项目规范，我可以快速浏览一下，也许我可以找到适合你的应用程序的东西。
问候，
埃米尔

Hi Tom,
You are welcomed.
Three outputs applications are not so common and indeed there are not to many transformers designs that you can choose from. But if you can share the project specifications, I can take a quick look and probably I can find something good enough for your application.
Regards,
Emil

你好汤姆，
我一直在寻找您的请求的现有解决方案，不幸的是我没有可用的东西。
但是，我仍然想帮助您使用自定义变压器，但我需要您提供有关应用/可能的未来机会的更多信息。
也许我们可以打个电话？
让我知道
问候，
埃米尔

Hi Tom,
I was looking for an existing solution to your request and unfortunately I do not have something available.
However, I would still like to help you with a custom transformer but I need more information from you on the application/possible future opportunity.
Maybe we can have a call?
Let me know
Regards,
Emil

嗨埃米尔：
实际上经过一段长时间的审查铁氧体磁芯电源变压器的相关信息，我认为我终于解决了这个问题（仅仅1天前）。似乎一些核心和组件制造商对组件参数使用略有不同的符号和方程式而且不熟悉它非常令人困惑。我不是100％，但我很顺利。
感谢您的提供，以帮助更多！
汤姆

HI Emil:
Actually after some long hours reviewing relevant info on ferrite core power transformers for isolated flyback SMPS I think I finally have this problem worked out (just 1 day ago).  It seems some core and component manufacturers use slightly different notations and equations for component parameters and not being familiar it was very confusing.  I'm not 100% but I'm well on my way.
Thanks for your offer to help more!
Tom
