摘要
This paper introduces a new wideband power meter based on the measurement of complex ratio of phasors using orthogonal decomposition technology, which enable active power measurement in 200Hz similar to 150kHz frequency rang effective. The range of voltage and current measurement also can be enhanced to 600V and 100A by AC voltage divider and AC current shunt. The experiment indicates power meter based on this measurement method has the advantages of wide frequency range and simple circuit structure, and it has great practical value.
