The invention relates to the field of low-voltage treatment of electric energy quality, discloses a module synchronization method applied to a symmetric bridge type voltage regulating device, and aims to omit a serial port and a communication line between a rectifier module and an inverter module. According to the method, a communication instruction between a rectification module and an inversion module is preset; the process of analyzing the communication instruction from a bus by the rectification module and the inversion module comprises the steps of collecting bus voltage, separating potential instruction signals according to a set value of the bus voltage of a direct current carrier wave, and extracting real instruction signals by using a direct Fourier transform algorithm or a correlation operation method, and executing corresponding operation according to instruction information; the process of loading the communication instruction to the bus by the rectification module and the inversion module compris
