SCR circuit using TCA780 and transistor amplification 59

Published:2011/4/17 21:08:00 Author:Nicole | Keyword: SCR, transistor | From:SeekIC

The SCR output current can reach 30A. Adopting potentiometer Rp1 can adjust output DC power. Because the integrated trigger TCA780 only has about 50mA output current, the SCR needs 1A control current, so it should connect a amplifier circuit composed of NPN tube.
