Tóm tắt

To supply high DC current to a single turn toroidal field coil of a spherical torus machine, it is an important engineering aspect that the operational losses should be minimized for the power supply system. As a switching element of an AC/DC converter, instead of a thyristor or diode, a power-MOSFET is a desirable component to be applied to a high current power supply system. The lowered resistance of parallel connected and pre-cooled power-MOSFET elements makes it possible to reduce the AC/DC converter power supply system losses. To output high DC current in one direction, the synchronous rectifier type AC/DC converter with parallel connected power-MOSFET elements is proposed as the power supply system for single turn toroidal field coil.
