High voltage capacitors for medical X-ray generators

Medical X-ray tubes run on tens to over a hundred kilovolts DC, usually produced by a high frequency transformer followed by a multi-stage Cockcroft–Walton multiplier. Each stage pairs one high voltage capacitor with a diode, so voltage margin and capacitance consistency directly affect output stability. Longxin B and E series discs rated 15–30 kV suit these multiplier stages and output filters; the E series is smaller in diameter at the same voltage, which helps in compact tanks and modules.

Typical equipment

• Medical X-ray machines
