Frequency converter control method and system, electronic equipment and storage medium

The invention discloses a frequency converter control method and system, an electronic device and a storage medium, and relates to the field of frequency converters, a master frequency converter and a slave frequency converter are connected through an expansion module, and the expansion module generates a reference carrier and a synchronization signal corresponding to the reference carrier by using a determined carrier period of a carrier signal output by the master frequency converter; and the synchronous signals are output to the main frequency converter and the slave frequency converters to enable carrier signals output by the main frequency converter and the slave frequency converters to be synchronous with the reference carrier, so that carrier synchronization between the main frequency converter and the slave frequency converters is realized, and synchronous control among the multiple frequency converters is realized. Errors in the control process caused by asynchronous signals are avoided, the reliabil
