Concept Map: Diversity of capacitor types used in electronics.

To Do:

1) Cite 4 examples of capacitor’s use in electronics.

2) What type of capacitor is each of the 4 you cite? Suggest how each is manufactured

do registers fit well inside an FPGA (why or why not?) Please answer the question clearly and readable

1.write a program for the msp430FR6989 to make led 1 blink at 50 percent duty cycle. 2 modify the program to make led 1 blink 5 times, make a long pause, then blink 5 more times then stop. The time delays should be carried out in subroutines

Write a program for the msp430 to make led1 and led 2 alternate blinking 2. repeat the program to make each led blink 5 times in a sequence, then 5 times simultaneously

A brief theory about Synchrony Motors. (Computer text only. 3 paragraphs minimum)

using code composer studio 1. write a program for the msp430fr6989 that will light LED1, whenever S1 is pressed. It should turn off whenever S1 is released.

2. Write a program that will make LED1 blink 5 times when S1 is pressed, and then stop.

Explain at least five NFPA codes or requirements related to leakage current limit in medical equipment.

DO HARDWORK To receive credit for this assignment, each problem must be computed using a MATLAB script. Do not hard-code computations. Define variables for the parameters given in the problem, and use MATLAB to calculate necessary intermediate and final output variables. Inlcude the MATLAB Code. A 200-mi. transmission line has the following parameters at 60 Hz: Resistance, r = 0.24 Ω/mi. per phase Series Reactance, x = 0.71 Ω/mi. per phase Shunt Susceptance, b = 5.42 × 10−6 S/mi. per phase Determine the signal wavelength λ and the propagation constant γ, attenuation constant α, phase constant β, and characteristic impedance Zc of the transmission line at 60 Hz using the general expressions in terms of Z and Y parameters valid for conductance G = 0 S/mi. Next, calculate the “convenient” artificial value for conductance G = RC/L and α, β, and Zc using this approximation. Finally, determine the sending-end voltage and current if the line is open-circuited and the receiving-end voltage is 100 kV line-to-line.

The torque generated by a PMSM by, is the (positive) magnitude of . If we control the angle  such that  , hence ,  then the PMSM becomes a Field Oriented Control BLDC motor generating the torque as .   On the other hand, the torque generated by a separately excited dc motor can be expressed by  (refer to lecture notes).   For permanent magnet DC motor, .

1.1      BLDC vs SEDC

Describe in detail terms how   and   are similar.  (Which term corresponds to which).

1.2      BLDC vs PMDC

Describe in detail terms how   and   are similar.   

1.3      PMSM vs PMDC

Explain the difference between   and  .    Explain why we don’t refer PMSM as a BLDC or DC motor.  

Develop a matlab script file to calculate the practical single phase transformer parameters. The program should ask the user to provide the following individually:

S_rated
V1_rated
V2_rated
With secondary shorted
P1
V1
With primary open
P2
I2

The program should calculate
Req
Xeq
Zeq

Gc
Ym
Bm

Make sure your code will pronmpt a message like: “Enter the real power at the primary winding when the secondary winding is shorted, P1=). Do the same for all parameters S, V1_rated, V2_rated, P1,V1, P2, I2

The program should return the outputs the form: “the shunt inductance susceptance, Bm=”,
do the same for all outputs.

Design a sine wave generator with adjustable frequency and amplitude. Show circuit diagram please!

Using Multisim

Verify the logic of the XOR and XNOR gates and compare to OR and NOR gates.

A) Orient the Word Generator and Logic Analyzer in the workspace and enter the appropriate settings. (BELOW)

B) To create the four gates you will need four 10K resistors and:

1) OR gate: a (7432)

2) NOR gate: an OR (7432) with an INV (7404)

3) XOR gate: a (7486)

4) XNOR gate: a XOR (7486) with an INV (7404).

C) Use outputs 00 and 01 of the Word Generator as inputs A and B for each of the four gates and connect them to the first two inputs of the Logic Analyzer.

D) Wire the outputs from the four gates to the next four Logic Analyzer inputs and connect each output to ground through a 10K resistor.

Fill in a Truth Table for each of the four gates
