Abstract

The invention provides a method and a device for processing a synchronization signal, and relates to the technical field of power supplies. The problems of low accuracy and low speed of synchronization operation for the synchronization signal are solved. The method specifically comprises the following steps of: acquiring signals to be processed of a plurality of power supplies, wherein the signals to be processed are periodically variable signals; generating pulses in each period of each signal to be processed, and generating a synchronization signal of which the period is the same as that of the signal to be processed, wherein each period of the synchronization signal comprises at least two pulses; detecting whether the synchronization signal is normal or not by judging whether parameters of all the pulses in the synchronization signal are accurate or not; and if the synchronization signal is normal, performing time calibration on the pulses in the synchronization signal to synchronize the signals to be processed. The method and the device can be applied to the synchronization operation for signals.

Description

technical field [0001] The present invention relates to the technical field of power supplies, and in particular, to a method and device for processing synchronization signals between multiple power supplies. Background technique [0002] In a power supply system, in order to achieve synchronous operation between two or more power supplies, it is necessary to send a synchronization signal to the power supply, and the power supply tracks the synchronization signal. [0003] By synchronizing the synchronization signals, one can realize the synchronous operation between two or more power sources, that is, synchronizing the original signals in the two or more power sources, and the synchronization signal is a signal with the same period as the original signal. [0004] There are many ways to generate synchronization signals, including: using hardware or software to obtain the positive / negative zero-crossing points of the original signal, generating pulses of the same width at th...
