【Abstract】 Closed phase angle has important effect on the dynamic behavior of AC contactors including contact bounce, especially. Using a device for selecting a certain angle to switch on circuit, the contact bounce of a pro- duct , with 80 A rated current, had been investigated under different angles experimentally. Then, with virtual prototyping technology, the dynamic behavior of the contactor has been simulated. Based on the above research, a synchronous control method for AC contactor was proposed.更多还原
