Sharp Observation: Noise-Free High-Voltage Power for X-ray Imaging
In high-end industrial X-ray real-time imaging systems, image clarity and signal-to-noise ratio directly determine defect detection capabilities. The system requires continuous, stable X-ray emission. Any fluctuations or noise in the high-voltage power supply will produce artifacts or noise in the image, obscuring critical information.
Power Supply Noise Impact on Image Quality
Ripple noise in the high-voltage power supply directly modulates X-ray intensity, resulting in:
- Uneven grayscale and fixed-pattern background noise
- Reduced visibility of small, low-contrast defects (microcracks, loose surfaces)
- Flickering streaks during dynamic imaging that affect judgment
Solution: Ultra-low ESR Doorknob Capacitors
Our high-voltage doorknob capacitors feature:
- Ultra-low equivalent series resistance (ESR) and inductance (ESL)
- Maintain extremely low impedance across high-frequency ranges (tens of kHz to MHz)
- Create a "current dead zone" for effective high-frequency ripple current bypass
- Deliver near-perfect DC high-voltage output
Customer Benefits
Improved Image Quality: Higher signal-to-noise ratios reveal micron-level defects
Enhanced Inspection Efficiency: Reduces repeated exposures and manual misjudgments
Increased System Reliability: Excellent heat dissipation ensures long life in continuous operation
Production Line Suitability: Ideal for in-line inspection equipment with stable performance
