AI Technical Summary
Technical Problem
Conventional power converters are susceptible to noise interference, resulting in inaccurate feedback signal sampling and difficulty in accurately sensing the output current.
Method used
The controller can adjust the operation of the power converter within a specific time window to reduce the impact of noise, such as by temporarily interrupting the switching operation, modifying the switching frequency, or adjusting the setpoint voltage, in order to perform accurate sampling during the noise window.
Benefits of technology
This improves the sampling accuracy of the feedback signal, reduces the impact of noise on the monitor, and ensures more accurate current or parameter sensing.

Abstract
本公开的各实施例涉及功率转换器控制和参数采样。一种装置包括控制器。控制器接收与由电源供电的设备相关联的反馈。与设备相关联的反馈的采样容易受到由控制器附近的功率转换器引起的噪声的影响。为了实现对反馈的更准确采样，控制器在电源对设备供电的时间窗口期间调节功率转换器的操作。经调节的操作减少由功率转换器引起的噪声，使得在功率转换器的操作被调节的时间窗口期间，控制器从所接收的反馈中导出一个或多个准确的样本值。
