Information × Registration Number 0213U002109, 0112U005384 , R & D reports Title Preparation for the design of AC non sinusoidal wattmeter for the measurement of power losses in induction elements popup.stage_title Head Tuz Yulian M., Registration Date 15-01-2013 Organization Radioengineering Department of National Technical University of Ukraine "K P I " popup.description2 New designs of wideband wattmeter based on finding the square of sum of the signals, which are proportional to the voltage and current in the load, were proposed; conditions of invariance of the square voltage and current in the load were found; solution of equations that describe the algorithm of the power meter was found, thus allowing to optimize input level on the criterion of the maximum band width; prototype of the wattmeter with single-channel measurement of square voltages proportional to sum and difference of voltage and current in the load; signal generator was designed, element of which is the investigated inductor; the method of wattmeter's input circuits calculation was developed.
