Design and Simulation of Gate Driver Circuit Using Pulse Transformer
Pulse transformer is always used to be the isolator between gate
driver and power MOSFET. There are many topologies about the
peripheral circuit. This paper proposes a new topology circuit
that uses pulse transformer to transfer driving signal and driving
power, energy storage capacitor to supply secondary side power
and negative voltage. Without auxiliary power source, it can
realize rapidly switch and off state with negative voltage. And a
simulation model has been used to verify it. The simulation
results prove that the new driver has a better anti-interference,
faster switching speed, lower switching loss, and higher
reliability than the current drive circuits.
