RANGKAIAN PENYEARAH SETENGAH TERKENDALI TIGA FASA UNTUK PENGENDALIAN KARAKTERISTIK MOTOR ARUS SEARAH SHUNT

Abstract

A modern control of electric motor’s speed in an industry needs a variable direct voltage. The variable direct voltage can be supplied by semiconductor devices such as SCR. The output voltage of a SCR rectifier depends on the delay angle of the
SCR. The aim of this research is to make a SCR rectifier circuit and applying it for observing the characteristics of a shunt direct
current motor. The result shows the circuit can work to demonstrate the shunt motor characteristics.
