A current sharing control method for parallel intelligent rectifier bridges is disclosed and applied to current sharing and rectification operation for a plurality of parallel three-phase silicon controlled intelligent rectifier bridges. Each intelligent rectifier bridge sends sampling data of a previous power frequency period to an adjusting device after receiving a zero-crossing synchronization signal, the adjusting device sets synchronization period timing after receiving first sampling data, and the synchronization period is limited to be less than one half of a power frequency period; in a set synchronization period, as for all the intelligent rectifier bridges, the adjusting device receives sampling data before replying control data for next power frequency periods corresponding to the intelligent rectifier bridges in a one-by-one manner, and each intelligent rectifier bridge sends sampling data only once in one power frequency period. Via adoption of the current sharing control method output currents of the parallel intelligent rectifier bridges can be equalized in an accurate manner, and a possible problem that various output pulses are not synchronous in parallel intelligent rectifier bridges can be effectively prevented. System operational reliability can be substantially raised.
