    Thank you for this very interesting video; thanks to this we learn a lot about the representation of signals and the use of the oscilloscope. As for picky audiophiles, I think their beliefs are more like philosophical conditions than physical evidence. The advantage of showing these measurements makes it possible to reestablish facts which have been established for a long time. Electrical physics is a science that cannot be questioned.

    thx for your effort. do you have experience with snubber networks and cap multiplier? I´m one of these audio guys ;)) I use line filter, but what regulator would you buid for an 50W + class A Power amp? -thx

    • @KissAnalog
      @KissAnalog  ปีที่แล้ว

      Great feedback and questions;) Yes, I will show how to design snubbers in a video soon. I typically use them in switching PS, but did you have another application for them? I'm going to design a switching PS in a Collab with JAT. I started some videos on this but I got side tracked. I'm just getting back on it.

      @@KissAnalog I believe snubbers are used between the transformer secondaries and the bridge sometimes to deal with HF noise at the point diodes are switching.

  • @ColinMcCormack
    @ColinMcCormack ปีที่แล้ว +2

    Does the switch-on voltage of the diodes create a minor dead band as the ac supply crosses zero?

    • @NZHippie
      @NZHippie ปีที่แล้ว +2

      Yes, it is a form of Distortion of the waveform...

    • @KissAnalog
      @KissAnalog  ปีที่แล้ว +1

      Thanks for the great question! Actually the diodes switch off when the AC voltage drops below the output voltage - as then they are not forward biased. That's why they are only on at the top of the waveform - well passed the zero crossing. The next video you will see more of a crossover distortion like in a Class B amplifier.

  • @pa3eka

    Wonder if you are so close to the max of the 160 VA Transformer that it is saturated in peaks

    • @KissAnalog
      @KissAnalog  ปีที่แล้ว

      Thanks Bert for the great question! No it isn't saturating and these transformers are usually pretty robust and derated a lot. The DC resistance does start to really show though - and it will start to get hot if left on too long. When you see the flat top and it actually rises at the end, that shows DC resistance where saturation would show it falling with current, and if it hard saturated it would be like a short.

    Would have been good to see how the waveforms varied at different loads, i e. Lighter loads. In audio gear transformers are not normally being run flat out like that all the time.

    • @KissAnalog
      @KissAnalog  ปีที่แล้ว

      Great idea! I'll do that with both this low freq switcher and the HF switcher in the next video that I did;)

  • @pa3eka
    @pa3eka ปีที่แล้ว

    Like to see the same setup , but lowering the load , because there is some sataturation of the torroid , but the triangle shape stay,s the same , i think , but make your own coffee , its a lot cheaper 😂

      It's bonkers ehh. Ever see the isolation toroid diodegonewild has. Looks like you could do brain someone with it. I got a 1kva hammond isolation transformer on a trade last year and if I dropped it I'm sure it would go through the floor. I'm going to use it to clean up some sort of ground fault loop caused by my recording studio monitors and sub being plugged in at the same time in my current workshop. I'm only looking for a purpose to justify it's existence as I shouldn't have taken it. I can't imagine what it costs to ship off ebay used but digikey still sells them. 30kg.

The F...ERS lied, they presnet adds/video of units, showing the two toroids insode, but when you buy you only get ONE toroid and the unit will do only 4kW (says 8kW continous on the outside and in THE SALES SPECS!).
