The disclosed circuitry supports effective power management for a multimedia display processor, which may include various components that operate separately from one another. In this manner, the disclosed circuitry can support power conservation and enhanced performance within a multimedia processing environment. In some aspects, headswitch or footswitch circuitry may be implemented to selectively connect and disconnect different logic components of a multimedia display processor to a power rail depending on the operating mode of the respective logic component, e.g., depending on whether the logic component is in an active or inactive mode.

Abstract: An apparatus, system, and method are disclosed for safely connecting a device to a power source. The invention includes a power bus switch that operates to selectively allow operational power to flow from a power supply to a load. The operational power is independent of auxiliary power which may be separately provided to the load. A detection module determines whether an input impedance of the load is greater than a minimum impedance threshold in response to the load being connected to the power supply. A switch module causes the power bus switch to allow operational power to flow to the load in response to the detection module determining that the input impedance is greater than the minimum impedance threshold. Thus, if the load has an acceptable input impedance level, then operational power may be provided to the load without risk of failure to the power system.

Abstract: Consistent with an aspect of the present disclosure, a method is provided for controlling an AC signal, which is supplied to a load and selectively supplied to a utility grid. In response to a fault in the utility grid, the method includes decoupling the AC signal from the utility grid, and determining whether a voltage associated with the AC signal is within a desired band. The method also includes adjusting the voltage associated with the AC signal when the AC signal is outside the desired band, and comparing a magnitude of a current associated with the AC signal with a desired current value to thereby obtain a comparison result. In response to the comparison result, the current associated with the AC signal is adjusted when the voltage associated with the AC signal is within the desired band.

Abstract: An electrical switching topology for a hybrid switch provides extremely low losses in both cryogenic and non-cryogenic electronic systems. In this switch having switch modules connected in parallel, switching losses in a first module are separated from conduction losses in the parallel-connected second module. The conduction losses are then further reduced by cryogenically cooling the second module. Since the switching losses of the first module can be absorbed outside a cryogenic container, the switching losses do not add to the cryogenic heat load. In other applications, the switching module operates at lower temperatures to provide higher switching speeds and reduces switching heat generation.

Abstract: A removably connected power supply for supplying external power to an electronic product. An output unit supplies power to the electronic product. A switching unit selects whether to supply the power to the output unit, and a switching apparatus turns on the switching unit in response to being connected with the electronic product and turns off the switching unit in response to being disconnected from the electronic product. The switching apparatus includes a switch which performs a switching operation in response to the connection or disconnection with the electronic product from the output unit. A switching element controls operation of the switching unit in response to the operation of the switch. Thus, the power supply is operated in a power saving mode and unnecessary power consumption and damage caused by voltage or current spikes are prevented.
