ELECTRONIC WATT-HOUR METER MANAGING MULTIPLE INPUT SIGNAL AND METHOD OF CALCULATING WATT-HOUR

摘要

The electronic power converter and the power amount calculation processing is possible for each of the input signal is disclosed. Electronic power converter includes a signal conversion that converts the multiplexer for selectively outputting any one signal of the analog form of the voltage and the signal sensing unit for sensing a current, the sensed voltage or current, to selectively output the signal to a digital signal part and, via the port corresponding to the converted digital signal, on the basis of the demultiplexer and outputting the converted digital signal, the converted digital signal, it characterized in that it comprises a computing unit for calculating the amount of power. Thereby, the power consumption can be reduced, thereby enabling a reduction in the size of the power converter.
