Hi,
In Elektor Labs there is an article about an Electronic load for DC and AC. May be it can helps. They use an DC Electronic Load behind a bridge rectifier for AC mode. https://www.elektormagazine.fr/labs/electronic-load-for-dc-and-ac The video https://www.youtube.com/watch?v=YXUa-xOSNLE&t= In attachemnt all the files of the project. Best regards. |

I would use a clamp on AC current meter or current transformer to get actual readings from the transformer. Don't rely on some pulsed DC on the load side.

By the way. You are aware that regarding current ratings. They are in AC. If you load your transformer with a typical setting with a rectifier and filter (inductor/capacitor) The DC current you should allow for. In some cases should be much lower than the transformer AC current rating.
Just in case this something new for you I leave this Google link for you https://www.google.com/search?q=Design+Guide+for+Rectifier+Use |

What exactly are you testing on these transformers...and why? I need to test nominal current and check temperature, the problem was the current is different and I need flexibility. --------- I think to use a classic DC mosfet dummy load and put a Graetz Bridge without capacitor, the current tha flow in the circuit is equal, the mosfet "sees" DC pulse current but this I think is not a problem. |

Hi
Both circuit are simple to simulate in LTSpice or Pspice just to know whether they work or not - you don't have to use same components just choose close parameters. All the best Bobi |

I found this link. Seems that's more or less what you sought (an AC constant current load).
