High Voltage Ultra-High Stability AC Voltage Amplifier Based on Magnetic Coupling

Abstract:

An alternating high voltage amplifier with four output ranges of 60/120/240/480V at power frequencies based on magnetic coupling and feedback compensation is presented. It is designed for calibration purposes. By the use of high quality transformers, a precise feedback loop and an error-correcting amplifier, a high gain stability and excellent performance over time is achieved. Its measured gain stability of amplitude and phase are within  0.2 V/V and  0.2 rad respectively over hours with a very low total harmonic distortion (THD) of 0.0022%.
