| Abstract: | The three-phase fully-controlled bridge pulse triggering device controlled by 89C51 is mainly introduced in this paper. This device controls angle ct as needed, calculates time by software, gathers simultaneous signals to realize timing by counter 8253 and outputs 6 pulse signals with an angle α to SCR gate. The hardware and software designs of triggering device controlled by 89C51 are discussed. The control accuracy and tuning range of this system are analyzed too. It has much value. |
