Abstract
A power supply device includes a master power supply module, a slave power supply module and a control module. The master power supply module is configured to output a master output current and an output voltage according to a master control signal. The slave power supply module is electrically connected in parallel to the master power supply module and configured to output a slave output current and the output voltage according to a slave control signal. The control module is electrically connected to the master power supply module and the slave power supply module and configured to output the master control signal according to the output voltage, generate a current compensation signal according to the master output current and the slave output current, and output the slave control signal according to the output voltage and the current compensation signal which is based on the master output current.
