Abstract
A method, device, and system for balancing a supply current in a Power Supply Units (PSUs). The system includes a plurality of PSUs connected in parallel to a power bus. The method includes detecting a falling edge in a common Load Share (LS) signal and, in response to detecting the falling edge of the LS signal, enabling a field effect transistor (FET) and starting a timer. Prior to starting the timer, a time trigger is determined for the timer based on a current output level of a power source in the PSU. The method includes outputting a current at the current output level for the duration of the time trigger and, at the time trigger, releasing the FET and resetting the timer. The PSU includes a processor that monitors the LS signal. The LS signal determines a timing for outputting current by the PSU.
