WebSCR Pulse Triggering. Using level triggering as described above has the drawback of creating gate current throughout the 'on' period of the SCR. This creates unnecessary gate current and in high power application can add to heat generated at junction 2 of the SCR, which in turn may reduce long term reliability. WebThis project is designed to give a smooth start to the induction motor based on the SCR firing triggered by heavily delayed firing angle during starting and then gradually reducing the delay till it reaches zero voltage triggering. This results in low voltage during start and then gradually to full voltage. lowest ranking njcaa school
