摘要： A conventional power supply device has a problem in miniaturization. A power supply device generates a prediction value of an error signal from first and second error signals, and controls an output voltage so that the prediction value lies between first and second threshold values. The first error signal is obtained by converting an error voltage based on the difference between the output voltage and a reference voltage at a first timing. The second error signal is obtained by converting an error voltage based on the difference between the output voltage and the reference voltage at a second timing.

摘要： A power device may include channels coupled to conductors in lines, where each one of the channels is coupled to a different one of the lines than the other channels and where the channels deliver direct current power signals over the conductors to the load devices. Each one of the load devices may be powered by a different one of the direct current power signals. The power device may include a power communicator that communicates with the load devices over the conductors that propagate the direct current power signals. The power communicator may determine a target power level for the load devices based on the communication over the conductors. The load device may adjust an amount of power in the direct current power signals in order to match the target power level.
