| Abstract: | Combining with the re.arch and development of high frequency pulse stimulating system applied in arc excited ultrasonic welding,in which the MOSFET being used.the turn-on and turn-off processes of MOSFET are presented,and then its requirements of electrical-isolated high-speed driver circuit are introduced.After that, the design and implementation process of MOSFET driver circuit, which meets the requirements including operation frequency up to 100 kHz,electrical-isolated,strong driving capability and antidisturbance capability,is discussed in detail.Experimental results show the feasibility of the driver circuit.The driver circuits introduced in this paper have also referential values for designing driver circuits of other voltage-controlled switches such as IGBT. |
