|  |  | | | | | 有上传，再次贴图，这里只仿真反激部分，不管PFC部分
 |
|
|
| | |  | | | | | | 大哥，能否加个QQ，也是有仿真的问题，请教下，谢谢，我的413097292 |

光偶打不开吗，如附件，再添加一次，麻烦帮忙看看，小弟学用这个软件有三个月了，老板现在想看进度， |
|
|
|
| | | | | | | | | | | 再添加一次看看，我这个光偶也是在论坛上找的，用分层电路的模式添加的 |
|
|
| | | | | | | | | | | | | 搞不懂为什么单POP仿真没问题，但是AC仿真却提示POP不收敛， |
|
|
|
| | | | | | | | | | | | | | | | | 将 Max. Period设置为 20u ，Cycles before lauching POP 为 400 以上即可。 |
|
|
| | | | | | |  | | | | | | | | | | | | 我试了还是不行，你能否帮忙用我上传的仿真文件修改下然后再回传给我，谢谢！ |
|
|
| | | | | | | | | | | | | | | | | | | | | Flyback_AC_Ref.rar
这个是软件代理商提供的教案，同样的问题，AC仿真报错，都是POP不收敛。
还有个问题是怎么才算POP收敛？
按您的提示我看进度条的收敛值都是2422%了，还不收敛？ |
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | 非常感谢大师，您改过的文件是可以仿真了，能否告知大师的仙名，日后还会叨唠您的， |
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | 为什么相位图会是这样啊，相伴不都是在正负180度范围内吗，怎么这个跑出700多度啊？
这是什么原因呢？
 |
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 我同样的应用条件还有一个不是用3842，而是用分立元件来产生PWM控制信号，那个仿真出来的结果跟实际值比较接近，还有嵌位部分好像不起作用啊？是怎么回事呢？ |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 大师，再请问下这个error code是什么意思啊，一开始都没问题，我只是想点击back-annotate后就出现这个错误代码，然后disable initial condition后还是不行。
*** ERROR *** (simplis_bjt.lb): Could not evaluate "ICINT=([1,2,3])[IC]"

|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 我有把这个问题反馈给simplis的技术支持，他们还跟我要了仿真文件，还没收到回复，应该晚点就会有了，到时再分享给你。
还有一个问题是3842启动前10ms内会有掉占空比的情况 ，如图，请问下这是为何？
 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 谢分享先。
Flyback 那个？我这里 run 没这情形。 |
|
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 这个是重新搭的，之前那个出问题了的输出是从0V开始上升 的。
看3845的规格书也没整明白是怎么一回事。 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2的 Initial Condition 是12V 啊。 |
|
|
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 开始的2.5ms，Photo-diode 是Off的，无反馈，看到的大电流是输出电容的充电电流。
不明白，互感添加到哪里去？ |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 因为我手上没有buck IC的库，想用3842来做buck,故想用互感来检测电流。 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current Transformer (CT) 也不过是变压器。 |
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 没用Outlook Express，打不开，请上传修改后 Simulation file。 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 新建文件夹.rar
SIPLIS的技术支持说他用6.2和7.0都没问题但是我用5.5还是有问题。 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Me too, V.5.5 , no luck .
See if the foillowing works :
1. Make a backup copy of the simulation files
2. Back-annotate the original
3. Copy all the IC's to the backup copy
4. Run the backup copy |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 您再帮忙看下这个仿真文件，3482做的DC-DC buck控制器，得不到设计值啊。
帮我看看是出了什么问题，谢谢！

|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current sense 需要的是电感电流上升的部分，不是下降的部分。 |
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 3845的duty cycle最大不超过0.5，你的设计已到极限。
把CT和RT改为100pF 和10K (保持Osc frequency 1.1MHz)，
输入20V，输出9V还是可以的。 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 嗯，我后来也发现了这个问题，请问你手头上有没有buck的专用IC库啊？
还有请教下下面这个是什么元件啊？
 |
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Totem pole driver (Building Block Lib - Control Elements - Drivers) |
|
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 针对这个问题，SIMPLIS的那哥说是因为咱用的是盗版的软件，正版的软件不会有那个问题，还有可以早请1个月的正版7.0的使用，license期限为1个月 |
|
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7.0 应该有很大改进，波形分离的功能，5.5也有，Curve- Stack all curves ，不知是否一样？ |
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 嗯，5.5的话，就要用 Axes- Edit Axis 来改变Y-轴的显示范围。 |
|
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 这个模块从6.1开始就有了，只是7.0是他的新版本，支持多core calculation.
针对DVM这个模块还在摸索中， |
|
|
|
| | | | | | | | | | | | | | | | | | | | | | | | | 我跟你的问题是一样的，请问大师是怎么给你改的？我也是单POP分析没有问题，但是AC分析就不收敛？ |
|
|
| | | | | | | | | | | | | | | | | | | 按您的提示设置仿真后，还出现下面这个错误代码？
看不懂，能否帮忙解释下？

上传仿真文件，请大师们帮忙看下，为什么提示这个错误代码？

| | | | | | | | | | | | | | | | | | | | | | | 你把C1即接3845的晶振脚的电容设一初始值即可。 |

我也遇到问题了
