Conclusions

the MOSFET’s working conditions, by increasing the temperature and switching losses, it

also worsens application efficiency and working conditions by fully modifying the device’s

switching behavior and doesn't achieve the converter values set by design. Moreover, a

sustain a higher temperature, as well as dissipating a larger power to charge up the

MOSFET input capacitance. It is also dangerous for producing the cross conduction that

may cause system disruption by the static dV/dt.
