AI Technical Summary
In existing technologies, the secondary power supply protection mechanism is difficult to adapt to the performance degradation under long-term high temperature and full load conditions, and lacks the ability to classify and process transient disturbances and permanent faults, resulting in a decrease in voltage regulation accuracy and fault misjudgment at the end of the power supply's life.
A degradation feature extraction algorithm is used to generate degradation feature vectors. An adaptive compensation algorithm is used to adjust the PWM duty cycle to restore the power supply voltage. Combined with a dual-defense mechanism, the system prioritizes adaptive compensation under transient disturbances and switches to redundant modules under permanent faults, thereby achieving autonomous recovery of the power supply system.
It effectively avoids test interruptions caused by incorrect switching, ensures rapid recovery of the power system at the functional level, realizes full-process autonomy from transient disturbances to permanent failures, and improves the reliability and stability of the power system.
