50 kW Sedecal SHF-530 X-ray High Voltage Generator Inverter Teardown
Вставка
- Опубліковано 10 лип 2024
- This Sedecal SHF-330, with HF meaning High Frequency, was originally a 37.5 kW x-ray high voltage generator. It later received an upgrade, to a Sedecal SHF-530, which is a 50 kW 500mA x-ray high voltage generator.

If that contactor is for functional, rather than safety isolation, it would only need to switch 2 of the 3 phases. I wonder if they keep one phase connected to avoid anything floating up to a very high voltage if an earth comes off
That is a very good point! That would leave a negative rail for faults to return through, if there was a capacitor from negative rail to ground... I do not remember if there were such, when I in a hurry pulled the inverter panel out of the cabinet.
Yesssss Ive been waiting for more X-Ray generator content. Im currently winding my own transformer for my own system!
Nice teardown 👍😎, definitely useful parts for future projects
Lets see if the PM300 can become a CM300 :)
@@KaizerPowerElectronicsDk I am excited to see
Nice teardown. Just a tip, you should include schematic of the power section with all passives measured and noted. Something like DiodeGoneWild does in his teardowns.
Never seen large bricks mounted to a chassis like that, no heatsink. Wouldnt that heat up a lot tho?
I think they only running in pulse mod, maybe also they driving the transformer in SLR (would explain the capacitor and inductor), I was built a SLR converter to drive a HV transformer for a Jacob's Ladder
@@Alexelectricalengineering SLR?
@@breezetixhv Series load resonant converter
@@breezetixhv It is a good topology for homemade HV Transformers since you can basically endlessly arc

i hope you asscemble all as it was? )
My guess is that parts will be reassembled as they should be. :) He only had access to that one cabinet in the system.
Not quite understood? Entire x-Ray systems are EASILY above 500 kg in total. It is not something you just slab in the back of your car :)
@@KaizerPowerElectronicsDk Exactly, you'll reassemble a few of the parts into other projects - as they should be :) Nice IGBT find, btw. I hope you were able to remove the back cover and have a look around.
