Abstract

The present invention provides a synchronization signal processing method and apparatus, which relates to the field of power supply technologies, and solves problems of low accuracy and a slow speed of synchronization operation executed on the synchronization signal. The specific steps include: acquiring multiple to-be-processed signals of a power supply, where the to-be-processed signals are signals changing periodically; generating a synchronization signal that has the same period as the to-be-processed signals by generating pulses in each period of the to-be-processed signals, where each period of the synchronization signal includes at least two pulse; detecting whether the synchronization signal is normal by determining whether parameters of all the pulses in the synchronization signal are accurate; and if the synchronization signal is normal, synchronizing the to-be-processed signals by performing time alignment on the pulses in the synchronization signal. The synchronization signal processing method and apparatus can be applied in a synchronization operation between signals.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a method and device for synchronous signal processing between multiple power supplies. Background technique [0002] In the power supply system, in order to realize 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] People can realize the synchronous operation between two or more power supplies by synchronizing the synchronizing signal, that is, synchronizing the original signals in the two or more power supplies, and the synchronizing signal is a signal with the same period as the original signal. [0004] There are many ways to generate a synchronization signal, which can include: using hardware or software to obtain the positive zero crossing point / negative zero crossing point of the original signal, generating a pulse of the same...
