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°.
