Abstract: A method for synchronizing startup of a plurality of power supplies in an electrical system includes supplying input power to a first power supply to supply power to an auxiliary converter and an auxiliary controller. The method also includes monitoring, via the auxiliary controller, a signal shared by each of the plurality of power supplies. The method further includes incrementally increasing, via the auxiliary controller, a value of the shared signal to a next incremental value of a plurality of specified values. The method also includes enabling, via the auxiliary controller, each of the power supplies to supply power to a load when the value of the shared signal is set to a maximum value of the specified values.
