If any of the algorithms below reaches a point where it oscillates three times around the MPP (i.e., it crosses the MPP back and forth three times at the same points), you can stop the simulation and report your results. Problem #1 – Incremental Conductance MPPT Method .
An ideal PV panel model can be used to understand the operation of the P&O method. Let the panel parameters be n=1, T=300K, IL=3A, and Io=10-10A.
a) Plot the I-V and P-V curves of the panel. b) Based on the I-V and P-V curves, what are the theoretical MPP, VMPP, and IMPP? c) Using a step size of ?V=0.1V, and starting at VPV=0V, implement the incremental conductance algorithm in a manner similar to the flowchart. Find the two values of VPV around which the oscillation occurs. d) Repeat part (c) for a step ?V=0.01V.
Let x(t) = u(t) u(t 1).Find the average signal y(t) using the above integral. Let T = 1. Carefully plot y(t).Verify your result by graphically computing the convolution of x(t) and the impulse response h(t) of the averager.
BJT can be used as a switching network. In this case, Q-Point jumps from one extreme of Dc Load Line to the other creating Saturation and cutoff conditions. What components in the configuration assure us of this operation
The sinusoidal flux in the core of a transformer is given by φ = 0.002 Sin 377t Wb. This flux links a primary winding of 100 turns. Determine the induced voltage in the coil as a function of time.
The average noise power per unit bandwidth measured at the front end of an AM receiver is 10^(-3) watt per Hertz. The modulating wave is sinusoidal, with a carrier power of 80 kilowatts, and a sideband power of 10 kilowatts per sideband.
The output is Z=1 if and only if the total number of 1's received is divisible by3 (0,3,6, ...) and the total number of 0's received isan even number greater than zero. (Hint: The minimum number of states is 9.)
Write a program to create an array initialized with Hex digits in the ROM space. The main code should copy this array to a different array in the RAM space.
Draw a state transition diagram for a state machine that reads in a sequence of binary digits, one at a time, and stops when it has read in five 1s (need not be consecutive). To "stop" the machine, merely have it orbit in the state
Explain the statement that induction motor is fundamentally a Transformer?
Determine the panel orientation you would choose to obtain maximum energy: (a) Over the year (b) In the summer (c) In the winter Discuss your choice of slope angles if the location is at 75°N.
A starship of mass (2.0?106 kg) uses its tractor beam to pull a shuttlecraft (2.0?104 kg) aboard from a distance of 10 km away. The tractor beam exerts a constant force of 4.0104 N on the shuttlecraft. Both spacecraft are initially at rest.
A transmission line of char. Impedance 100ohm is used to match a 50ohm section to a 200 ohm section. if the matching is to be done both at 429MHz and 1GHz the length of the transmission line can be approx?.
A 40 kHz sinusoidal voltage has zero phase angle and a maximum amplitude of 2.5 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady-state current has a maximum amplitude of 125.67
