Abstract: A manufacturing system includes a tape advancing through the manufacturing system and a station of the manufacturing system. The tape includes a first portion having grains of an inorganic material bound by an organic binder. The station of the manufacturing system receives the first portion of the tape and prepares the tape for sintering by chemically changing the organic binder and/or removing the organic binder from the first portion of the tape, leaving the grains of the inorganic material, to form a second portion of the tape and, at least in part, prepare the tape for sintering.

Abstract: Power supply hold-up time is increased using regenerative braking. A power line disturbance (“PLD”) event is detected in a power supply unit. One or more fan motors associated with the power supply unit may be signaled to provide regenerative braking based on identifying the PLD event, where the one or more fan motors transition from a motor operating mode to a regenerative braking mode. The regenerative braking may be applied to the one or more fan motors associated with the power supply unit, where a hold-up time is extended to prevent shut down of the power supply unit.

Abstract: A discrete VRM card comprises a set of VRM controllers. The set of VRM controllers comprises a VRM controller with two feedback loops. The VRM card comprises a power stage and a power-stage critical-signal multiplexer. The output of the power-stage critical-signal multiplexer determines a feedback loop with which the power stage communicates. The VRM card also comprises a configuration selector. The configuration selector determines a feedback-loop assignment for the power-stage critical-signal multiplexer and provides VRM instructions to the VRM controller.

Abstract: A phase-redundant voltage regulator apparatus includes groups of regulator phases, each having a multi-phase controller (MPC) connected to each regulator phase. The MPC transfers, to control logic, phase fault signals and a pulse-width modulation (PWM) phase control signal received from each dedicated regulator phase of a phase group. Spare regulator phases include output ORing devices to limit current flow into spare regulator phase outputs. Output switching devices are configured to electrically couple spare regulator phase outputs to a common regulator output. Control logic is connected to the phase groups MPC and asserts phase enable signals to, transfers PWM phase control signals to, and receives phase fault signals from the spare regulator phases. The control logic electrically interconnects a spare regulator phase to a phase group including a failed regulator phase in response to receiving a phase fault signal from an MPC.
