power MOSFET isolated gate drive circuit

Published:2011/6/7 20:09:00 Author:John | Keyword: isolated gate

Power MOSFET isolated gate drive circuit is just as shown in the figure. In the circuit, pulse signals input to terminal A and B are from the switching power supply integrated controllers such as TL494 or UC3852. T1 and T2 are pulse transformers, which aim to provide high-low voltage isolation and enhance the ability of anti-noise. Therefore, high power switching circuit can work reliably. Circuit’s duty cycle can be adjusted with a range from 0% to 45%. Switching characteristics of power MOSFET are quite related to the ability of the gate drive. VT3 and VT4 here all use PNP-type transistors in order to rapidly discharge accumulation of charge between the power MOSFET's gate and source pole , thereby reducing its on / off delay time.   (View)
