A boost converter has 5 V input and 12 V output at 60 W. The diode is ideal. The transistor requires 1 uS to turn on or off. The switching frequency is 100 kHz. The storage components are large.
a) Plot the current and voltage waveforms associated with the transistor? (Hint: KVL and KCL must be satisfied, and an ideal diode carries current only when it is on)
b) What is the switching loss in the transistor?
How many volts must be applied to a 3- ohm resistor to result in a power dissipation of 752W 3) A 0.27-k ohm resistor is rated 2W. Compute the maximum voltage that can be applied and the maximum current that it can carry without exceeding it..
a) Plot the spectrums for the range from 0 Hz to 25000 Hz. Make sure to label the frequncies. b) sketch the recoverd analog signal spectrum if an ideal lowpass filter with a cutoff frequncey of 4.5 kHzis used to filter the sampled signal.
