Design a micro grid of PV rated at 100KW of power and at 230 V AC using a PV module with the following voltage and current characteristics. Determine the following:
Number of modules in a string for each PV type
Number of strings in an array for each PV type
Number of arrays
Inverter specifications
One-line diagram of the system
A capacitor is made with very large plates separated a distance d. The potential between the plates is V=1000 volts and d = 1mm. a) Calculate the pressure the plates exert on the air between the plates.
Use MATLAB to compute the inverse Laplace transform of X(s)=(s^2+2s+1)/(s(s+1)(s^2+10s+50)) and determine the value of x(t) in the steady state. How would you be able to obtain this value without computing the inverse? Explain.
The project has been broken down into the following modules: Power supply, Processor and motherboard with RAM, I/O circuit board, CD-ROM drive, Floppy drive LCD display, Keypad, Enclosure and all mechanical parts, Final assembly.
With a 500hp shunt wound DC motor, at 1800rpm, 500Vdc, FLA is 800Adc, Ra is 0.025 and Rf is 400. What would Va need to be if you wanted the motor to operate at 1000rpm at rated torque. Keeping the field current constant.
Using many resistors and the DMM, try to determine what digits each colour band represents. Briefly explain your method and your findings in the space below.
A HCS12 embedded timer is in PWM mode. If the E-clock is 24 MHz, and a scaler value of 16 is selected, what is the period for a signal with PWMPER = 0x75
Design a circuit that will multiply the input voltage by +12. That is the output voltage is 12v1 where v1 is the input voltage. All resistors should be at least 12ohms.
Suppose you are the supplier and can produce 20 units now but cannot start production on the second 20 units for two months. What price would you try to negotiate for the last 20 units?
What is the data rate of a digital electrical communication system that uses 16 voltage levels to carry multiple bits with one voltage level, where each voltage level is kept at that level for a duration of 2 ms
Consider the interval [0,30]: y[n+2] - 0.6y[n+1] - 0.16y[n] = 5x[n+2]. a.) Find zero-state response if the input is x[n]= 4^(-n)u[n] b.) Find zero-state response if the input is x[n]= cos(2npi/6)u[n]
What do the letters PCM and PAM stand for? Why is PCM transmission preferred over PAM transmission? Give at least two reasons in your answer.
the frequency response h(e^jw) of a length-4 finite impulse response filter with a real impulse response h[n] that the following specific value: h(e^j0)=13, H(e^j3pi/2)=-3-j4, and h(e^jpi)=-3. determine the 4th discrete fourier transform (DFT) of ..
