    Hi John, Inject capacitor cannot be increased to that high value. It cannot be beyond 22nF in the system. You should probably use other knobs to fix the saturation - maybe regulator side Y-caps. Could you please try this and share us the plots? we would…

    Hello Niu, In the simulations that you are running, you have to look at the noise ripple at the grid level by connecting a LISN as shown below We recommend plotting EMI spectrum on the grid side to look at how it improves when the device is OFF to device…

    I checked my settings and they are the same as yours, but it still can't converge. However, I found a way, which is to set the cycles before launching POP higher (200). If anyone has this problem, you can try my method. Thank you.

    Part Number: TPSF12C1 Tool/software: Does TPSF12C1 work with 9 ~ 36V DC power? If so, what is the neccesary changes need to be made in order to do so. The datasheet only have AC/DC example Thank you

    Hi Naresh, Do you have any update? I will also add a supplement to [Question 2]. If the INJ waveform is saturated, the following measures can be considered. • Increase the capacity of the Y capacitor (regulator side) to a value larger than the value currently…
