三相平衡式單可控硅充電電路的研究
THE INVESTIGATION OF A THREE-PHASE CHARGING CIRCUIT BALANCED WITH ONE THYRISTOR
-
摘要: 本文根據(jù)蓄電池充電的特點,提出了一種僅僅使用一只普通的可控硅輪流控制三相的平衡式充電電路,它克服了一般單相和三相可控硅充電電路的缺點,而又吸取了后兩種電路的優(yōu)點。它以最簡單的方法實現(xiàn)在整個范圍內(nèi)的三相處處同步調(diào)節(jié),這就打破了在三相平衡電網(wǎng)中,要使三相達到平衡,必須用多只可控硅來同步調(diào)節(jié),以實現(xiàn)輸出直流電壓調(diào)壓的傳統(tǒng)做法。這為可控硅充電設(shè)備的設(shè)計提出了一種既簡單、又經(jīng)濟、且三相能平衡調(diào)節(jié)的可控硅實用新電路。

Abstract: Based on the specific requirements of battery charging, a three-phase balanced eharg-ing circuit controlled with one thyristor is proposed. This circuit is free from the defects existing in general single-or three-phase thyristor charging circuit but has the abvantages of the both. It is capable of achievement of three-phase synchronous re-gulation throughout the whole range by a simple way. Thus, it is different from the traditional method. there is no need to adopt multi-thyristor in three-phase balanced network to balance and synchronize the regulated D.C. output voltage. The purpose of this paper is to present a new practical circuit which is not only simple, economic, but also able to be three-phase balanced in voltage regulation, thus providing a good design of charging equiplent controlled with one thyristor. -
