亲爱的,我正在使用谐波平衡模拟8个二极管,而且耗时太长。
虽然瞬态模拟“仅”2-4小时,但这种模拟仍在进行(至少22小时......我担心计算器),并且它仍在尝试寻找第5个二极管爆炸的解决方案。 我想知道什么是“二极管爆炸”,主要是如何减少电路的仿真时间,即使它降低了二极管模型的精度。 如果您有任何建议或提示,请帮助我。 谢谢,问候,Landlack 以上来自于谷歌翻译 以下为原文 Dear all, I'm simulating 8 diodes with HARMonic Balance, and it's taking too long. While the transient simulation took "only" 2-4 hours, this simulation is still going (it has been at least 22h ... I fear for the calculator), and it's still attempting to find solutions for the 5th diode explosion. I would like to know what is the "diode explosion" and, mainly, how to decrease the simulation time of the circuit, even if it reduces the accuracy of the diode models. If you have some suggestion or hint, please help me. Thank you, Regards, Landlack 附件

爆炸电流由二极管模型中的Imelt参数设置。
如果未定义该参数,则默认为Imax参数值。 如果未明确定义,则默认为1安培。 如果器件电流过高,那么器件工作在高度非线性模式,这将导致模拟时间增加,因为模拟器越来越难以检测收敛。 以上来自于谷歌翻译 以下为原文 The Explosion Current is set by the Imelt parameter in the Diode Model. If that parameter is not defined then it defaults to the Imax parameter value. This in turn defaults to 1 Amp if it is not explicitly defined. If the device current is too high, so the device is operating in a highly non-linear mode, then this will cause the simulation time to increase as it gets more and more difficult for the simulator to detect convergence. |

所以在实践中我需要引入“二极管模型”对象,并降低Imelt电流值;
我一直在模拟的设备是由ADS库完成的,所以我不完全知道如何模拟它们。 我会试试,谢谢你,问候,Landlack 以上来自于谷歌翻译 以下为原文 So in practice I need to introduce the "diode model" object, and decrease the Imelt current value; the devices I've been simulating were taken by the library of ADS, so I don't know perfectly how to simulate them. I'll try, thank you, Regards, Landlack |
