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. This x-ray generator comes in 3 different versions. Line powered drawing all power directly from mains, 20-50 kW. Capacitor …

I do a teardown and test of a Victron Energie Atlas Combi 12-800. It is a combined battery charger and 230VAC inverter. The battery charger of the Atlas Combi is suitable for a 230 VAC, (50 Hz) mains voltage. The charger works automatically, so batteries may remain permanently connected to the charger, even during winter …

Variable Isolation Transformer are different from a variable transformer, like a variac. Isolation from mains gives greater safety. Teardown of a variable transformer, which provides a variable voltage and isolation. Single phase 1x250V @ 3A.
I give a short introduction to the differences between autotransformers, variable autotransformers and variable transformers. I show my collection of 7 variac transformer / variotransformer in the range from 1x260V @ 2A to 3x400V @ 25A along with a 3x400V 10kVA isolation transformer. 3x400V @ 13A Variac demonstration with data monitor: https://www.youtube.com/watch?v=PqeLLLZTBb8 You might wonder …

I give an overview of a 65kW X-ray generator system for a 70 kV X-ray transformer. The full-bridge of 400A 1200V IGBT bricks makes for a powerful inverter to drive the ferrite cored high voltage transformer.
I go through my collection of current transformers. Regular ratio transformers, hall effect sensors, shunts, Pearson and Ion Physics current monitors and how to make a DIY high frequency current transformer.
I go through my collection of iron/ferrite core high voltage transformers. MOTs, OBITs, NSTs, PTs and X-ray transformers. Microwave Oven-, Oil burner ignition-, neon sign- potential- and x-ray transformers. I forgot to add the old and new flyback transformers I have… somewhere…
Teardown of the Siemens Polyphos 30 X-ray head which contains step-up transformers, voltage multipliers and a rotating plate x-ray tube and a lot of oil! Be sure to check out part 2 about the collimator and image plate and part 3 X-ray inverter system. Discussion of teardown and additional pictures: https://highvoltageforum.net/index.php?topic=523.0
