1. A synchronization method for multi-channel signals, applied to a first power supply module, wherein the first power supply module is connected to at least two mutually isolated second power supply modules, the method comprises:
allocating target data information and a same target duration to each of the second power supply modules according to total data information pre-input by a user, and
synchronously transmitting a clock signal to each of the second power supply modules, and triggering each of the second power supply modules to output a data signal corresponding to the target data information with an output duration of the data signal being controlled to be equal to the target duration based on the clock signal,
wherein in the step of allocating target data information and a target duration to each of the second power supply modules, different second power supply modules are allocated with same or different target data information.
