Test and evaluation of lighting system in high-frequency AC microgrids

A 600 Hz single phase high frequency AC microgrid is proposed to integrate the renewable source and load. In order to provide insights of how lighting systems can be adjusted to work more efficiently with high frequency power source. This paper is devoted to a study of the illumination intensity and efficiency changes of current household lighting systems under high frequency operating conditions. Comparisons of performance under different working frequencies are explained. Two types of lighting system, incandescent lamps and fluorescent lamps with magnetic ballast, were tested and evaluated. The experiments results of current & input power, illumination intensity and illumination efficiency, heat, power factor and starting voltage of lighting system have been obtained. It was determined that both types of lighting systems can function when directly plugged into 600 Hz AC source, and that they have superior performance and higher efficiency using a 600 Hz than a 60 Hz system.
