Abstract: Embodiments for linking separate eFuse and ORING controllers for output overvoltage protection in power conversion applications. Voltage regulators are configured in parallel. An input circuit includes an input controller, the input circuit being coupled to an input of at least one voltage regulator of the voltage regulators. An output circuit includes an output controller, the output circuit being coupled to an output of the at least one voltage regulator. The output controller is coupled to the input circuit to cause the input circuit to prevent power to the at least one voltage regulator in response to the output controller detecting an overvoltage condition.

Abstract: Embodiments include redundant power supplies and method for fault detection in a redundant power supply. Aspects include monitoring a voltage at local output nodes of each phase of the redundant power supply, wherein the local output nodes are each connected to an output bus of the redundant power supply via a feedback path. Aspects also include creating an alert that a phase associated with the local output node has failed based on a determination that the voltage at the local output node is within a fault range.

Abstract: Electric power devices and control methods are provided which automatically select a line voltage or phase voltage of an AC voltage supply. The electric power device includes a switchable circuit, a sensor and a switch control. The switchable circuit connects to the AC voltage supply, and includes multiple switchable elements. The sensor ascertains a voltage level of the AC voltage supply, and the switch control automatically establishes a configuration of the switchable circuit through control of the multiple switchable elements. The switch control couples the electric power device in a line-line (delta) configuration to the AC voltage supply when the voltage level is in a first voltage range, and a line-neutral (wye) configuration when the voltage level is in a second voltage range.
