AI Technical Summary
Existing fiber optic isolated transmission technology faces challenges in high-voltage power electronics testing scenarios, including complex high- and low-frequency signal separation calibration, inherent DC bias signal distortion of optoelectronic devices, and difficulties in real-time calibration of end-to-end gain variations.
The system employs a combination of a signal input module, a signal transmission module, a bias adjustment module, and a DC measurement module. The DC measurement module detects the DC bias loss during signal transmission and generates compensation parameters. The bias adjustment module generates a DC bias compensation signal, simplifying the calibration process and achieving accurate compensation of DC bias and gain across the entire link.
It simplifies the high- and low-frequency separate calibration process, achieves accuracy and efficiency in the signal transmission system, and ensures long-term stability of signal transmission and ease of engineering implementation.
