A buck converter has the following parameters: Vs = 24 V, D = 0.65, L = 25 uH, C = 15 uF, and R=10 ohm.The switching frequency is 100 kHz. Determine (a) the output voltage, (b) the maximum and minimum inductor currents, and (c) the output voltage ripple.
a. Neglecting resistance, determine the synchronous, transient and sub-transient reactances. b.If the machine is delivering 1.0 p.u. current at 0.8 power factor lagging at the rated terminal voltage when the short circuit is applied.
Consider a thin ring of radius a with uniform charge density and total charge Q. The ring is cut in half across the diameter and the two halves superimposed to double the effective charge density.
Identify the types of system-building methods used by Dorfman to build its wireless warehouse system.
y(t) + 0.2(dy(t)/dt) = x(t) a. Find y(t) if x(t) = 6(e^-2t)u(t) and y(0) = 3. b. In a. identify the zero-input and the zero initial condition part. c. In a, identify the systems-type and the input-type part.
Two particles are fixed to an x axis: particle 1 of charge q1 = 2.03 x 10-8 C at x = 16.0 cm and particle 2 of charge q2 = -4.62q1 at x = 77.9 cm. At what coordinate on the x axis is the electric field produced by the particles equal to zero
The voltage drops across three resistors in series are measured to be 10.0V, 15.0V, and 25.0V. If the largest resistor is 47.0 ?, what is the value of the smallest resistor?
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
A flyback converter is to be designed to provide 10V at 18A from a smooth 200V source. Isolation between the input and output is required. The switching frequency is 200kHz and the duty cycle is 0.4.
A PN junction has Na=10^19 cm^-3 and Nd= 10^16 cm^-3. a) with V=0 what are the minority carrier densities at the depletion region edges Assume V= 0.6 V for (b)-(d). b) What are the minority carrier densities at the depletion region edges
An infinitely long cylindrical dielectric of radius b contains charge within its volume of density ρv=aρ^2, where a is a constant. Find the electric field strength, E, both inside and outside the cylinder.
a patron of a casino doubts that the dice used in the casino are balanced. During a visit she rolles a die 100 times an got an even number only 30 times. A. formulate the hypothesis you would use to test whether the die is fair.
A slotted line is used to measure the voltage maximums and voltage minimums on a transmission line with a characteristic impedance of 50 . The voltage maximum is measured as 7.5 V and the minimum is 5 V. The line is terminated with a purely resist..
