Q13. A buck converter is constructed with a MOSFET which has an
on-state resistance of 75m?, and a diode with a forward voltage
drop of 1.3V. The MOSFET exhibits switching rise and fall times of
50ns. The converter operates from an input voltage of 400V and. The
converter supplies 1.2kW at an output voltage of 300V and switches
at 150kHz. The MOSFET and the diode are mounted onto separate
heatsinks. The ambient temperature in which the power converter
operates is...
