Seeking Advice on Replacing SRK1001 Synchronous Rectification Controller in Flyback Topology Simulat

[nesrine12]

Hello ST Community,

I'm currently working on simulating a flyback topology using VIPERGaN100 and SR1001 for synchronous rectification control in eDsim. However, I've encountered an issue as the SRK1001 synchronous rectification controller is not available in the simulation environment.

I'm reaching out to ask for advice on how to proceed with replacing or simulating the SRK1001 IC in my setup. I'm open to suggestions on creating a substitute or any alternative methods to achieve the synchronous rectification control required for my simulation.

Any insights, tips, or recommendations on how to tackle this issue would be greatly appreciated. Thank you in advance for your help!

Hi,

same here :

Why not use the sync rect controller SRK1001 , if you want sync rect ?

here:

https://www.mouser.de/ProductDetail/STMicroelectronics/SRK1001?qs=%252B6g0mu59x7J5PdgXIuMbaQ%3D%3D

about 1 $  -- is this the problem ?

hello, the problem that i want to do simulation and the srk1001 is not available in st edsim software

> the srk1001 is not available in st edsim software

So you can decide:

A: take other sync.rect. chip, that  you have a model for

B: write a model yourself

C: build it real and test it (maybe fastest way here,to come to a result)

i found other chip that have simplis model but when i install the model file and insert it in simplis it said that it is only compatible with simetrix simulator. and i work on st edsim software on simplis simulator because i have other component in my schematic wich is the vipergan100 that runs only on simplis.
