Single phase semi-converter have been made using SCR. Semi-converter is a controlled rectifier that work at single quadrant so that voltage and current output only have positive value. The aim of making this system is to get voltage variation, and controlled ellectricity and current. Triggering account is necessary in triggering SCR which obtained from triggering circuit that consist of microcontroller AT89S51 as voltage control circuit, modul IC TCA 785 as phase control and account transformator as firing circuit. Voltage control circuit connected with dipswitch as output and the output in the form of voltage variable that used as voltage control then synchronized AC’s phase source by phase control circuit. The output of phase control circuit in the form of triggering account can be shifted from 350 to 1800 then getting insulation from firing circuit. Output from firing circuit is used to triggering single phase semi-converter that use thyristor with kind SCR TIC 106. Result of examination of this system is that SCR’s triggering angle can be shifted from 350 to 1800. In single phase semi-converter examination, using lamp and motor burden, can be concluded that current and voltage burden increasing inversely proportional to triggering angle and phase shift can resulted in the change of DC motor speeds from 99,9 rpm until 0 rpm.
