AI Technical Summary

Technical Problem

Conventional high-frequency power supply signal acquisition systems continuously collect and output voltage and current signals without interruption, leading to inaccurate data during switch switching and in PULSE mode due to the inclusion of lamp generation phases.

Method used

The method involves determining rising and falling edge intervals within the current pulse period and setting data bits in the sampling array to 0 or a null signal during these intervals, using sampling delays or resets to mask abnormal data segments.

Benefits of technology

This approach ensures accurate data acquisition by outputting 0 data during switch switching and PULSE mode, and power only during correct time periods, thereby improving data accuracy.

Abstract

The present application discloses and provides a method and apparatus for collecting high-frequency power supply signals. The method includes determining a rising edge section and a falling edge section within a current pulse period, and setting data bits corresponding to the rising edge section and the falling edge section in a sampling array to 0, a low level of the signal, or a null signal. In the prior art, a collection board continuously collects voltage and current signals without interruption and continuously outputs the signals. Even during the switching of the switch and in the PULSE mode, the signals are still collected and output without interruption during the ramp generation stage, resulting in the problem of inaccurate data being output.
