Sharp Observation: Providing Noise-Free High-Voltage Power for Industrial X-ray Real-Time Imaging Systems
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, and consistent X-ray emission. Any fluctuations or noise in the high-voltage power supply will produce artifacts or noise in the image, obscuring critical information. This places extreme demands on the smoothness and continuous power output capabilities of the high-voltage power supply.

Challenge: How does power supply noise affect image quality?

Ripple noise in the high-voltage power supply directly modulates the intensity of the X-rays, resulting in:

Uneven grayscale in the image and fixed-pattern background noise.

Small, low-contrast defects (such as microcracks and loose surfaces) become difficult to discern.

Flickering streaks appear during dynamic imaging, affecting judgment.

Solution: Ultra-low ESR doorknob capacitors achieve "dead zone" filtering.

Our high-voltage doorknob capacitors, with their ultra-low equivalent series resistance (ESR) and low equivalent series inductance (ESL), are key to solving this problem. They maintain extremely low impedance even in the high-frequency range of switching power supplies (tens of kHz to several MHz), creating a "current dead zone" that effectively bypasses high-frequency ripple current, resulting in near-perfect DC high-voltage output.

Core Value for Customers:
Improved Image Quality: Achieve higher signal-to-noise ratios and cleaner X-ray images, revealing all micron-level defects.

Improved Inspection Efficiency and Reliability: Reduce repeated exposures and manual misjudgments caused by image quality issues, improving inspection throughput and accuracy.

Enhanced System Reliability: The capacitors' excellent heat dissipation characteristics (low ESR results in low self-heating) ensure long life and stability under continuous high-load operation, making them particularly suitable for in-line inspection equipment on production lines.
