A MOSFET and diode is used in a circuit shown in figure. The operating conditions are as follows:

Input Voltage = VIN = 42 V, Io = 5A. Switching frequency fs = 400 kHz, Duty-cycle = D = 0.3. Diode Forward Voltage drop = 0.7V. Diode Peak Reverse Recovery Current = IRRM = 2.5 A. ON-state resistance of the MOSFET is RDS (on) = 25 mΩ. VGG as a step voltage between 0V and 10 V. MOSFET timings – Td (on) = 50 ns; tri = 20 ns; tfv = 15 ns; td (off) = 25 ns; trv = 20 ns; tfi = 15 ns. Diode timing – ta = 12 ns; trr = 20 ns.

a. Draw and label turn-on and turn-off characteristics waveforms of MOSFET with respect to MOSFET gate-source voltage VGS waveform.

b. Draw and label diode voltage and current waveforms, assuming it to be ideal. Also draw reverse recovery characteristic of diode by considering its given practical data.

c. Calculate the average conduction loss in the MOSFET.

d. Calculate the average switching power loss in the MOSFET.

e. Calculate the average conduction loss in the Diode.
