Abstract

A plurality of power supply modules having their outputs coupled in parallel are controlled for load balancing purposes through a digital communications channel. The digital communications channel may be a wired digital serial or parallel bus, and/or a wireless digital communications channel such as Bluetooth, infrared, etc. Each of the plurality of power supply modules may broadcast their respective output currents and all of the plurality of power supply modules may determine a total current supplied to a load and thereby determine an appropriate output voltage for proportionally contributing to the total current.
