| Abstract: | This paper introduced a thyristor trigger control system of three phase full control bridge based on the singlechip controller of which control angle could be changed. The phase locked loop PLL was helpful to realize synchronization between the touch impulse and the power signal. The system has strong anti jamming ability and good touch impulse symmetry. It can produce six groups of the touch impulses under the control of software. The cost of the instrument is lower than the former ones. |
