摘要
Abstract
The cable traveling with the elevator car is not aesthetic and needs a periodic maintenance. In order to be freed from the cable,this paper designed a novel contactless power system of elevator car without traveling cable, realized the functions of contactless energy transmission by using high frequency loosely coupled transformer. The elevator car uses electricity from lead-acid batteries when it moves vertically,and the contactless energy transmission is closure. When the elevator car stopping at any floor,the contactless power system receives the arrival signal,resumes energy transmission and charges lead-acid bat-teries. This idea can improve the power supply efficiency and decrease the high frequency electromagnetic pollution. This paper analyzed the equivalent circuit model of loosely cou-pled transformer,and the influence of the working air gap,operating frequency,compensa-ting capacitor and so on to the supply efficiency was also studied. Finally,we designed a simple and efficient charger of high-power switching power supply, which had a better effect in voltage regulation characteristics and a high reliability in work.关键词
