摘要

为球面电机的单匝环面磁场线圈提供高直流电流，使供电系统的运行损耗最小化是一个重要的工程方面。功率- mosfet作为AC/DC转换器的开关元件，代替晶闸管或二极管，是应用于大电流供电系统的理想元件。并联和预冷功率- mosfet元件的电阻降低使得降低AC/DC转换器供电系统的损耗成为可能。为了在一个方向上输出大的直流电流，提出了一种功率- mosfet并联的同步整流型AC/DC变换器作为单匝环形场线圈的供电系统。

Synchronous rectifier using power-MOSFET for high current AC/DC converter system

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.

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
