Consider three level converter it suppllies 600Vrms line to line, 60Hz, balanced 3 phase fundamental voltage. each dc link capacitor is 2.0 kV. 1.Using sine triangle modulation at 1.8kHz, determine and plot 60Hz one complete cycle of line to line load voltages. Use of MathCAD is highly recommeded. 2. Using space vector modulation of 1.8kHz switching cycle frequency, determine appropriate vectors and switching times for a single switching interval when the output of phase a is Va(t)=60*2^0.5*cos(2.x.f.t)*V The balanced 60Hz waveform sample that we must modulate is the point where t=4.4ms. The DC voltage from rail to rail is 300V. assume the q axis and a axis are in same direction. The use of mathCAD is recommended.
List a state table for JK flip-flop, using Q as the present and next state and J and K as inputs. design the sequential circuit specified by the state table.
While an inductor is being energized the current flowing through it as a function of time is: i(t) = 56 (1 - e(-4600 · t) ) mA, for all times t > 0 and t is in seconds. What is the inductance, if a voltage drop of 1.188 V is measured across this indu..
the Mars Rover Spirit got stuck in the Martian sand. The wheels kept slipping. Attempts to free it were futile. Discuss the type of actuator in this case. Can you suggest any improvements in the actuator that would have prevented this unfortunate ..
Explain how to use the knowledge of Structure-Property-Processing-Perfomance relationship to improve on a device based on semiconductivity. Name the device, describe how it is made, the principle guiding its function and application.
Consider a myelinated fiber in which th nodes of Ranvier are spaced every 2mm. The resistance of the axoplasm per unit length is r(initial) = 1.4x10^10 omega/m. The nodal capacitance is about 1.5x10^-12 F.
Consider the design of an optimal linear filter for a zero mean WSS random sequence whereby the sample values during the observation window are given by: (-1,0,1,2,3,3,2,1,2,3,1,-1,-2,1,0) 1. Obtain the optimal memory M=2 linear predictor coeffecie..
The Emf generated in each conductor of a 6 pole simplex wave winding is 0.48V. If the Armature has 42 slots and 125 commutator segments and there are 4 turns/coil. Calculate the terminal voltage of the dc generator
A long copper wire of circular cross-section and resistance 0.05 O has a potential difference of 0.10 V applied across its ends. The wire is then melted and reformed into a wire of circular cross-section that is twice as long.
look at the sun through goggles that have been coated with a thin layer of highly conductive metal such as silver. BRiefly explain why and in which way the color of light will be altered.
The local building regulations prohibits construction of buildings higher than 25 m. Determine if it is possible to mount the antennas right at the roof top or if antenna masts to raise the height are needed. In the later case, what should the hei..
