Systems and methods for increasing power measurement accuracy for power factor correction (PFC) are disclosed. An exemplary method may include providing a PFC circuit for a power supply, the PFC circuit having a bulk capacitor connected to a rectified AC line. The method may also include measuring output load. The method may also include enabling AC wave skipping if the measured output load drops below a threshold value.

An electrical connector for transmitting electrical power includes at least one power pin with an ablative tip. The power pin has a body oriented in a direction of a longitudinal axis, and the ablative tip is at a terminal end along the longitudinal axis. The ablative tip includes a terminal edge and a support material positioned on a transverse side of the terminal edge that provides structural support to the terminal edge.

An uninterruptible power supply (UPS) includes a rectifier configured to receive alternating current (AC) power. The UPS further includes a first output connected to the rectifier through an inverter. The first output is configured to output an AC power supply. The UPS also includes a second output connected to the rectifier through a battery backup and a stepdown converter. The second output is configured to output a direct current (DC) power supply in response to a detected power anomaly condition, thereby providing extra redundancy that allows for increased power availability and uptime.

A system includes reception of a first portion of a firmware image, determination, based on the first portion of the firmware image, of whether to update the firmware based on the firmware image, transmission of an acknowledgement signal if it is determined to update the firmware based on the first portion of the firmware image, reception of a remaining portion of the firmware image, and updating of the firmware based on the firmware image.

A power supply unit includes a set of primary circuits operably coupled to a set of phase pair electrical inputs. The electrical inputs provide an input voltage via alternating current. Each primary circuit receives a phased pair electrical input of the set of phase pair electrical inputs and provides a tap output. A single transformer is operably coupled to each tap output. A single secondary circuit is operably coupled to the transformer to provide an output voltage via a direct current.

A power cord is described that includes “in-line” power control functionality. The power control functionality may selectively enable or disable a flow of electrical current through the power cord and/or selectively control an amount of electrical current that is permitted to flow through the power cord. The power control functionality may be activated and/or controlled through the receipt of control signals from an external device. The power cord may be configured to monitor the state of an electronic device to which it is connected and selectively activate and/or modify the operation of the power control functionality in response to the detection of a particular state of the electronic device. The power cord may also be configured to receive and analyze sensor data, and based at least on the analysis, selectively activate and/or modify the operation of the power control functionality.

A power supply unit (PSU) dynamically limits total recovery current. The PSU includes at least a power input, a power output, a historic maximum power draw memory, an update logic, and a recovery current limiting logic. Some implementations include a latest power measurement register, an hourly max power register, and a rolling max register, and controlling firmware. The update logic monitors a power level. The update logic updates the historic maximum power draw memory to match the monitored level. After a power interruption, the recovery current permitted to flow into the PSU is limited based on the historic usage. The recovery current may be limited in a constant, stepped, or ramped manner. The PSU may also provide power distribution. Multiple PSUs may be treated as a group, allowing an individual PSU to exceed its historic usage while the group's recovery currents are limited to the sum of historic usage levels.
