A buck converter has an input of 6 V and an output of 1.5 V. The load resistor is 3 , the switching frequency is 400 kHz, L 5 H, and C 10 F.(a) Determine the duty ratio. (b) Determine the average, peak, and rms inductor currents. (c) Determine the average source current. (d) Determine the peak and average diode current.
A farmer owns two barns; one north of a creek and the other south of the creek. The farmer has a Cabbage, a Goat, and a Wolf. The Farmer needs to put each item in a barn every night. If the Cabbage and Goat are in the same barn
Consider a 6 cm2 dye sensitised solar cell with reverse saturation current Jr=10-10A/cm2. When the solar irradiance is 1,000 W/m2, it produces an equivalent photo current/short circuit current of 15 mA/cm2 at 300 K.
The open circuit test on a single-phase 15kVA, 7500/480 V, 60 Hz distribution transformer yielded the following: V = 7500V; I = 0.2006A; P = 180W Calculate the core parameters RC and XM and the magnetizing current IM.
A 1 W power source is connected to the input of a directional coupler with C=20 dB, D=35 dB, and an insertion loss of 0.5 dB. Find the output powers (in dBm) at the through, coupled, and isolated ports. Assume all ports to be matched.
If AC is a sine wave and DC is a straight line, what would the wave look like on a graph if they combine. How/what to calculate to get this new waveform.
A Si pn junction diode is described by its I-V equation, I?= Is exp (V?/V?) ,where V?=25mV, Is=10-14A . It is desired to derive constant drop and PWL models for the diode assuming an operating current between 1mA and 3mA.
Evaluate the TL parameters. Include the effect of the earth as ideal. Do not incorporate the effect of the shield wires.
2.25 kg of a fluid having a volume of 0.1 m^3 are contained in a cylinder at constant pressure of 7 bar. Heat energy is supplied to the fluid until the volume becomes 0.2 m^3. If the initial and final specific enthalpies of the fluid are 210 kj/kg..
One step in decoding a simple code without knowing the coding scheme , involves counting the number of occurrences of each character. Then, knowing that the most common letter in English is "e" the letter that occurs most commonly
a). Develop a function with the name myAMmod to modulate the message signal. Use a carrier frequency fc=200hz. Plot the magnitude spectrum of the message signal and the modulated signal and explain the difference between them.
A president, secretary, and treasurer are to be chosen from a group of 10 senior members of the IEEE student chapter at the Citadel. Assume that each member cannot serve more than one position.
How does a transistor switch compare to a mechanical switch In other words, a mechanical switch when it is ON has a zer impedance. What about the transistor switch
