IGBT开关式励磁调节器研究

Research on IGBT Switch-Excitation Regulator

ＩＧＢＴ是一种新型功率器件，ＩＧＢＴ开关式励磁调节器是一种新型励磁调节器。它比ＳＣＲ或ＧＴＲ元件构成的开关式励磁调节器有优点，在中小型水轮发电机上有着广阔的应用前景。本文简述其原理、特点及在机组上的应用。

IGBT is a new type of power device,IGBT switch-excitation regulator is a new type ofexcitation regulator.This type of excitation regulator is superiOr to those excitation regulatorsformed by SCR or GTR elements. It opens up a broad prospect for beinng used in medium andsmall hydrogenerators.This article gives a brief account of its principle,characteristics and practical examples used in the hydroelectric sets.
