    摘要: Apparatus related to power factor are provided. A power supply provides regulated power to a load or loads. The power supply is coupled to a source of alternating-current (AC) voltage. A controller monitors the AC input voltage and a current loading of the power supply. The controller determines an activation time according to the monitoring and asserts a signal prior to a next zero crossing of the input voltage. The signal causes impedance circuitry to be coupled between a pair of input nodes, resulting in a lagging power-factor. The impedance circuitry is de-coupled from at least one of the input nodes after the zero crossing.

    摘要: An electric energy distribution system may include plural loads configured to receive electric energy from a common feed or branch. Each of the loads may be configured to operate in at least first and second modes such that it may consume current, VA or power up to a first cap when running in its first mode and up to a second cap when running in its second mode. The first cap may be higher than the second cap. A sensor component may monitor a parameter that corresponds to an aggregate amount of electric energy being consumed by all of the plural loads from the common feed or branch. A manager component may be configured, when the parameter meets or exceeds the threshold, to select one of the loads currently running in its first mode and to cause the selected load to run in its second mode.
