Abstract :
Applications and needs of high-frequency power supplies in industrial zones, chemical and steel plants, and commercial areas are investigated. The applications of the higher frequency and the selection of the frequency are discussed in detail. The conclusion drawn is that the suitable frequency seems to range from 400 Hz to 1 kHz. Energy and space saving applications of the higher frequency to fluorescent lighting, amorphous metal core transformers, DC power supplies, and naturally commutated cycloconverters are experimentally demonstrated. In addition, it is shown that the conventional thyristor AC voltage controller can be used for a soft starter of very high-speed induction motors.<>
