  • Abstract
    The principal advantage of an AC power system over a DC power system in spacecraft is the use of transformers for changes in voltage. To reduce transformer weight, the power system frequency is chosen in the range of 400 Hz to 20 kHz. However, power transformers operated in this frequency range may generate unwanted acoustic noise. Measurements of the acoustic noise generated by representative power transformers over this frequency range are reported. Recommendations are given for transformer design when acoustic noise is a concern
