FesZ Electronics | DIY - High voltage mechanical SMPS @FesZElectronics | Uploaded September 2019 | Updated October 2024, 4 hours ago.
#48 In this video I look at a mostly forgotten way of building switching supplies - by using relays!. It's quite an interesting idea that was used on a large scale and mass produced at one point to generate the high voltage used in vacuum tube circuits but since its various problems it became quite rare and forgotten. So just to be clear, there are other ways of building SMPS not just with semiconductor components but also electro mechanical component.

#117 In this video I start testing the LISN to see just how good it is. I look at multiple things starting with output impedance then go for insertion loss, input impedance and input side filtration and finally look at inter-channel isolation or cross talk.
