| Zusammenfassung | A highly accurate ac power source for unity power factor with an expected total uncertainty of a few parts in 106 to be used in the power frequency range continuously readjusted to a precisely known dc reference voltage using a multijunction thermal converter. A reference current is derived from the output voltage using an accurately known resistor. The output current of a transconductance amplifier is compared to this reference current by means of a current comparator and continuously readjusted. |
