Solution Overview
Problem
Existing synchronization signal processing methods in power supply systems suffer from low accuracy and slow speed due to the inability to determine the normalcy of individual pulses and the limited number of synchronization operations per period, resulting in inefficient synchronization between multiple power supplies.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If one pulse is included in each period of the synchronization signal, then the synchronization signal structure is simple, but the synchronization operation speed is slow
Solution Approach 1:
The synchronization signal is segmented into multiple pulses within each period, allowing multiple synchronization operations to be performed simultaneously or in sequence within the same period, thereby increasing the synchronization operation speed without requiring additional signal periods
Solution Approach 2:
Multiple pulses are generated periodically within each synchronization signal period at specific phase points (such as zero-crossing points), enabling repeated synchronization operations to be performed at regular intervals within each period, thus improving overall synchronization speed
2Measurement precision
If only the time interval between pulses is detected, then the detection method is simple, but the determination accuracy of pulse normalcy is low
Solution Approach 1:
The detection method examines local characteristics of individual pulses by comparing the time interval between adjacent pulses, allowing determination of whether each specific pulse is normal based on its relationship with neighboring pulses, thereby improving pulse normalcy determination accuracy
Solution Approach 2:
The detection mechanism uses feedback from the time interval measurement to determine pulse normalcy, where the measured interval is compared against expected values to provide information about the normalcy of individual pulses, enabling more accurate identification of abnormal pulses
3Productivity
If only one synchronization operation is performed per period, then the synchronization process is simple, but the synchronization efficiency is low
Solution Approach 1:
The synchronization process is segmented into multiple independent operations, each associated with a specific pulse within the synchronization signal period. This allows multiple synchronization operations to be performed in parallel or sequence within the same period, significantly improving synchronization efficiency
Solution Approach 2:
By incorporating multiple pulses within each synchronization signal period, the useful synchronization action continues throughout the entire period rather than being concentrated in a single operation, maximizing the utilization of each signal period and improving overall efficiency

AI summary
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.
