The embodiment of the invention provides a power module inter-machine communication method and a power module, the power module comprises a host and a slave, the method comprises the steps that when the host and the slave are in a first state, first information is transmitted on a communication path between the host and the slave in a serial port communication mode; when the host computer and the slave computer are in the second state, second information is transmitted on the communication path between the host computer and the slave computer in a pulse width modulation (PWM) communication mode, and the second information comprises indication information used for controlling the operation parameters of the slave computer; wherein the first state comprises a standby state, and the second state comprises an operation state; thus, the communication mode between the power supplies in the power supply module is improved, the communication path of the serial port communication mode is multiplexed, the transmission rate of the indication information is improved, the overall response speed is improved, no communication path is added, and the cost is prevented from being increased.
Description
technical field [0001] The present invention relates to the technical field of power supply, and in particular, to a communication method between power supply modules and a power supply module. Background technique [0002] With the wide application of high-power power supplies, not only are the requirements for performance indicators such as accuracy and reliability higher and higher, but also power supply requirements of various voltages and power levels are emerging one after another. In this case, the power module composed of multiple power supplies connected in series and parallel is more and more recognized by the market. The power module achieves a higher overall output capability. [0003] When multiple common power supplies are running in series and parallel, one of the power supplies is generally set as the master, and the other power supplies are slaves. The serial port communication, CAN communication and other paths are used between the host and the slave to c...
