Teardown of SCR inverter controller, driver and bridge for a General Electric mobile x-ray unit, the AMX-II. Features a 120V battery operated apparatus from 1979 which has a 60 Hz mains inverter and 500 Hz high voltage inverter. All analog controlled with completely custom made electronics.

Mads, nive bit of kit - any plans for it ?

On a visit to someone in my local hospital I had a walk around and discovered a repair department,
after some chit-chat I I was given (unofficial) permission to dumpster dive / skip salvage.
I got some neat stuff from there, but no longer as I can't travel.

So, when you are well and fit - visit your local hospital.

Cool!
Also relevant: old portal detectors sometimes have "interesting" parts in them.

No plans other than saving some of the best looking parts, like SCRs.

A 500 Hz transformer is not that practical and I have other much newer ferrite core hv transformers that I want to take for a spin instead, but that has to wait for another day :)

Damn neat mate! Very interesting setup in terms of the battery and frequency! Where/how did you find it?
