Given a buck-boost converter (with ideal components): 8 V. Vin 40 V.; Vo = 15
V. (regulated); C = 470 micro Farads; and fs = 20 KHz.
(a) Determine minimum L to ensure CCM operating mode if Po 2 W.;
(b) Determine 4Vo (peak-peak ripple) if Vin = 12 V., Io = 250 mA, L = 150 micro Henries
what would be the advantage, if any, of using a general equilibrium analysis to answer this question? Illustrate diagrammatically.
Determine the position x and the tension in the cord that is required for equilibrium. The cord passes through the smooth ring at B and has an unstretched length of 6ft and stiffness of k = 50lb/ft.
design op amp circuit to produce output vout which is related to inputs v1, v2 and v3 by expression vout= -(3v1+5v2+8v3). assume max permitted resistor value= 200k. use only one op amp
In a certain n-type region of a semiconductor in thermal equilibrium, there is a hole concentration with the following spatial distribution: po(x)=103(1 9×103x)cm 3 for0 x 10 4 withxincm Assume that in this region, the electron mobility and hole mob..
Describe in you own words how a modem works and what steps the data goes through to be sent from one terminal to another via modem.
Low doped silicon is used in partide detectors, in order to obtain a wide depletio region. Consider a pn junction with p-side doping Na = 5 X 1012 cm-3 and n side doping Nd = 1017 cm ".
A load is delivering 1400 VARs of reactive power at a power factor of 0.96 leading. Determine the complex power S and the average power P for the load.
Calculate the minimum PWM frequency for a small permanent magnet DC motor with a time constant of 15 milliseconds.
In a motor control system, one master stop pushbutton (Stop) is available for stopping the operation at any time. If the temperature switch (TSW) is closed, pressing the red pushbutton (RedPB) will turn on both motors M1 and M2.
Shuffle a deck of cards and pick two cards at random. Observe the sequence of the two cards in the order in which they were chosen. (a) How many outcomes are in the sample space
A bar phantom is imaged by an LSI system which is modeled as an ideal moving average system. The PSF of the system is h(x,y) = rect(x/delta, y/delta) (a) If bar separation of the bar phantom is f what is the output of the imaging system
If the voltage across a capacitor is a square wave, predict the resulting current waveform (draw the voltage and current waveforms). Repeat the process when the voltage across the capacitor is a sine wave.
