Abstract
This paper presents an electromagnetic propulsion system using high frequency AC (Alternating Current), and power supply suitable for this system. It is known that poisonous gases are generated by electrolysis when DC (Direct Current) flows through sea water. The electrodes are also corroded. The electrolyte is generated even if low frequency AC, such as commercial frequency, flows through sea water. Therefore, it has been proven that generation of electrolytes is suppressed when a high frequency AC is applied to this system. However, gases are generated by electrolysis when DC component is contained in high frequency AC.
In this paper, the characteristics of various power supplies are evaluated. In particular, four kinds of inverter, namely full bridge high frequency inverter, SEPP (Single Ended Push Pull) high frequency inverter, series resonant load and parallel resonant load inverters were compared and evaluated. Finally, a power supply suitable for an electromagnetic propulsion system is proposed.
