a) A 50kW separately excited DC motor has armature resistance of 2.5W, armature inductance of 30mH and back e.m.f of 100V when the motor is fed from a buck converter with 250VDC input, 50Hz switching frequency and 50% duty cycle. Assuming continuous conduction and lossless converter, find out the maximum, minimum and ripple currents in armature.
b) Determine the values of inductor and filter capacitor for a buck converter with following specifications: Input= 48V, output = 24V, Load curernt = 6A, switching frequency = 20kHz, ripple current = 30%.

The Ethernet standard uses CSMA/CD as a MAC protocol, whereas
the WiFi networks uses
CSMA/CA. Consider you are using your Home LAN mostly for
transferring streaming media
such as video, audio, and playing online games. Analyze your
knowledge of medium access
control protocols and point out which protocol would you use? Do
justify ?
