Q3.
a) Make a comparison between the five switching devices commonly used in
power electronics equipment. The comparison should cover the power
capability, switching speed, drive control types and controllability of those
switching devices.
b) A buck converter shown in figure Q3.1 is driven at a switching frequency of
1XY kHz. The load, R is at 10 Volts, 2.XY Amperes and the input voltage is
50 Volts DC.
i)
Find the value of inductance, L required to guarantee continuous
conduction.
Find the valuc of output capacitor, C to hold the output voltage ripple
below 0.1% and 1% respectively.

Where XY is the last two digits of your student number, the dot is a decimal point and
not a product. For example: If your student number is c1900123, the switching
frequency in part (a) is 123 kHz and the current is 2.23 Amps.
