Abstract
A digital current equalization method includes: acquiring a current value from a counter preset value loading module in each synchronization period; generating a continuous variable frequency pulse according to the current value, and receiving a synchronization signal transmitted by a phase inverter connected to the PFM generator; transmitting, according to the synchronization signal, the continuous variable frequency pulse to the digital current equalization bus through an OC gate of a triode connected to the PFM generator; counting a frequency of the continuous variable frequency pulse on the digital current equalization bus, where an acquired frequency count value is used to represent a current magnitude of a power supply module, which currently outputs a greatest current, of the foregoing power supply module and a power supply module connected in parallel with the foregoing power supply module to accordingly adjust the output current of the foregoing power supply module.
