| Abstract: | This article introduces the application of MSP430F449 microcontroller in the control system of intelligent synchronous vacuum switch.this system can control turn-on and turn-off time of the high voltage switch making use of the zero-pass signal and by adopting phase voltage and electric current of the electrical network.,it can be connected when the voltage is zero and it can be broken away when the electric current is zero. then it can eliminate the wave-like electric current with capacitive load and the inductive voltage with inductive load .this system can also figure out the effective number of phase voltage and electric current and power factor,monitoring the run parameter of the electrical network anytime. |
