Abstract

This paper describes the implementation of a new quantum-based system for the generation of 120 V rms, 5 A rms, sinusoidal, active and reactive power over the 50 Hz to 400 Hz frequency range. The system accurately relates the spectral amplitudes and phases of the voltage and current waveforms of the generated power to a programmable Josephson voltage standard (PJVS) using a novel differential sampling technique. The system also employs a new voltage amplifier that performs self-calibration and corrections of gain and phase errors. Details of the system design, measurement techniques, and significant sources of error are presented.
