Realization of an ultra-stable audio frequency electrical power calibrator

Year: 2024

Type: article

Abstract: The article introduce the design and implementation of an ultra-stable audio frequency electrical power calibrator, with voltage range up to 1 kV, current range up to 20A and frequency range from 20 Hz to 20 kHz. The 1 hour stability of its output power can reach to 25 ppm. It has good potential application for precision calibration of audio frequency power meters, energy meters, amplifiers and transducers.
