Abstract

Aim at the inconsistencies of trigger phase-shifting in integrated analog SCR trigger circuits caused by the dispersity of components

a digital SCR trigger circuits is designed based on FPGA and single-chip.Preprocessed analogous signals is converted to digital quantities by A/D.Through pulse synchronizing

phase shifting

the qualified pulse for SCR is produced at last.The results show that these digital SCR trigger circuits have high precision

the difference of trigger angle α is with in 0.09°～0.66°.
