X ray power supply circuit.
This series of tutorials explains in depth power supply design steps for the buck and the boost topology dc dc switching regulators supplemented by dedicated sessions on pcb layout and signal edge control for emi that apply to all switching regulators.
The three main parts to an x ray generator setup are an x ray tube a high voltage power supply and a control unit.
I took some time out to look at the circuit and came up with a quick schematic.
A detailed look at my high voltage x ray transformer.
Primary circuit control panel main switch.
Virtually all the filament power supplies spellman uses in their x ray generators and monoblock x ray sources are current sources not voltage sources.
