full wave controlled rectifier using RC triggering circuit

Abstract: speed control of dc motor using ujt scr example, assume that we want to trigger an S2010L SCR with a 32 V trigger DIAC. A 0.1 F capacitor will supply the necessary SCR gate current with the trigger DIAC. Assume a 50 V dc power supply, 30º minimum , , the DIAC triggers leaving 0.66 VBO of DIAC voltage on the capacitor. In order for DIAC to trigger , C1 reaches breakover voltage (VBO) of the DIAC, C1 is partially discharged by the DIAC into the , R2 120 V (60 Hz) R2 3.3 k C1 0.1 F Figure AN1003.9 Diac HT34B 68 k Figure
