<p>A digital current equalizing method and a power supply module. The digital current equalizing method comprises: acquiring a current numerical value from a counter preset value loading module in each synchronous period; generating a consecutive frequency conversion pulse according to the current numerical value, receiving a synchronous signal transmitted by an inverter connected to a PFM generator; transmitting the consecutive frequency conversion pulse to a digital current equalizing bus through an OC gate of a transistor connected to the PFM generator according to the synchronous signal; counting the frequency of the consecutive frequency conversion pulse on the digital current equalizing bus, and using the obtained frequency count value to represent the magnitude of the current of the power supply module with the maximum output current in the power supply module and a power supply module connected to the power supply module in parallel; and adjusting the output current of the power supply module according to the magnitude of the current of the power supply module with the maximum output current. Digital current equalizing may be realized on the premise that a chip does not need custom-making, so that the cost of digital current equalization can be reduced, and the universality of digital current equalization can be improved.</p> |
