AI Technical Summary
Traditional digital signal control methods struggle to maintain strict linearity of gain across a wide load and input voltage range in power supply systems. This results in decreased control accuracy, slow response speed, significant overshoot or undershoot, and insufficient adaptability to changes in system parameters. This increases design complexity and debugging difficulty, and affects system stability and robustness.
An adaptive linear gain adjustment mechanism is introduced, which combines high-precision signal acquisition and digital processing, dynamic gain curve correction and robust feedback control strategy. The target control gain is calculated by the adaptive linear gain adjustment module and dynamically corrected by the gain linearization processing module. A pulse width modulation signal is generated to adjust the power supply output, and real-time sampling and quantization feedback are performed to achieve gain linearity and fast response over a wide range.
Maintaining strict linearity of control gain over a wide load and input voltage range improves the response speed and stability of the power supply system, enhances its adaptability to parameter changes, and significantly improves the overall performance of power management.
