    摘要: A regulated current-fed power system employs power branching units connected in series. Each power branching unit includes a plurality of parallel-redundant converter groups connected in series with each other within a current path for the regulated current. Each parallel-redundant converter group includes at least two direct current (DC)/DC converters connected in parallel with each other, each sharing the power load. A protection device connected in series with each DC/DC converter disconnects the respective DC/DC converter from the regulated current when the respective DC/DC converter short circuits, with the remaining DC/DC converter(s) then receiving more of the power load. An active clamp connected in parallel with all of the DC/DC converters within a parallel-redundant converter group temporarily sinks a portion of the regulated current when one of the DC/DC converters fails in a short-circuit condition. The active clamp shunts the regulated current around all DC/DC converters within the parallel-redundant converter group converters fail in a short-circuit condition.

    摘要: A power converter magnetics assembly is disclosed. The power converter magnetics assembly can include an interface panel, a magnetic component mounted to the interface panel to form a magnetics subassembly, and a chassis coupled to the magnetics subassembly. The chassis can have a cavity with an opening. The magnetic component can be received within the cavity and the interface panel can be disposed over the opening and secured to the chassis to form an enclosure about the magnetic component.

    摘要: A system includes a power converter configured to convert input power into output power. The power converter includes first and second converter bridges, where each converter bridge includes multiple transistors. The system also includes a zero-voltage switching (ZVS) assistance circuit having first and second inverse controlled rectifiers (ICRs). Each of the first and second ICRs is configured to provide current to the transistors in the first and second converter bridges. The system further includes a controller configured to control operation of the first and second converter bridges and the ZVS assistance circuit. The controller could include a phase-shift modulation (PSM) controller configured to control the converter bridges and a pulse width modulation (PWM) controller configured to control the ZVS assistance circuit. The PWM controller can be configured to apply pre-shaped voltages to transistors in regulators of the ICRs to enable substantially zero-loss turn-off commutation of the transistors in the regulators.

    摘要: A computer-implemented method includes measuring, by a first local controller connected to a first converter, one or more characteristics of the first converter. The first converter belongs to a set of two or more converters in a power system configured to power equipment, and each of the two or more converters is connected to a respective local controller. An arc fault is detected based at least in part on the one or more characteristics of the first converter, and an indication of the arc fault is communicated to the central controller. The arc fault is remediated by performing one or more remedial operations determined by at least one of the first local controller and the central controller.
