| Abstract: | A DC power supply control system is introduced,which takes the MCU-controlled thyristor trigger pulse as its core and realizes the synchronous trigger pulse signal,phase shift signal,drive signal and over-voltage/over-current protection.DC power supply output voltage and output current are adjusted through the keyboard controller,and the actual value is displayed by LED.The control segment realized determination of the phase sequence of the three-phase AC power supply,synchronization of pulse formation,dete... |
