Abstract :
A new 20 Hz-20 kHz magnetoresistive watt-converter has been constructed. It has less than 0.5% non-linearity in the power range up to 40 W and less than 0.5% change in sensitivity in the whole frequency band. The converter has complex sensitivity at the frequency of 1 kHz equal to 25.9 exp(j 0.0015) mV/w*.
