Abstract: A power supply circuit for use with a power supply system. The power supply circuit can be provided within a power supply module connected with one or more additional power supply modules as part of the power supply system. The power supply circuit includes an optocoupler and a resistor ladder connected to the optocoupler. The circuit asserts a synchronization signal responsive to the optocoupler being energized.

Abstract: A power supply system includes modular power supply modules interconnected via a wire harness. The power supply system can be installed in one or more electrical cabinets in a manufacturing facility, for example, among other possible applications. The wire harness includes a fault bus and a synchronization bus, and the individual power supply modules detect and report faults as well as synchronize operation, such as pre-charging, via communication using the wire harness.
