The embodiment of the invention provides a synchronous starting circuit and method. According to the synchronous starting method, each power module in a plurality of power modules sends a conduction request signal to a synchronous starting bus, a synchronous starting module in each power module detects a running state of the synchronous starting bus, the synchronous starting module in each power module enables a power supply corresponding to the synchronous starting module to be conducted when the synchronous starting bus is changed to a second running state from a first running state, namely, the synchronous starting module detects the running state of the synchronous starting bus in real time, and the power supply corresponding to the synchronous starting module is conducted when the running state of the synchronous starting bus is detected to be correspondingly changed, so that synchronous starting of the plurality of power modules is achieved. Compared with an existing starting method, the synchronous starting circuit and method provided by the embodiment of the invention has the advantages that the synchronous starting of the plurality of power modules can be achieved, and the problem that time difference of a plurality of power supplies during starting is not beneficial for normal running of large-size equipment is solved.
Description
technical field [0001] The present invention relates to the field of circuit devices, in particular to a synchronous starting circuit and method. Background technique [0002] When supplying power to large-scale equipment, a large current is often required, and a large current often requires multiple power supplies to operate in parallel to provide it. [0003] The existing multiple parallel power supplies often cannot be started at the same time when they are started, and there will be time differences between multiple power supplies when they are started, so that the actual voltage and current received by large equipment cannot reach the rated voltage and rated current. It is not conducive to the normal operation of large equipment. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a synchronous starting circuit and method to improve the problem that there are time differences between multiple power supplies when starti...
