1- A switch-mode dc-dc converter is operating at a switching frequency of 20kHz, and Vd=150V. The average current being drawn by the dc motor is 8.0 A. In the equivalent circuit of the dc motor, Ea=100V, Ra=0.25 ohm, and La=4mH.a). plot the output current and calculate the peak-to-peak ripple andb). plot the dc-side current
2- the motor goes into regenerative braking mode. The average current being supplied by the motor to the converter during braking is 8.0A.a). Plot the voltage and current waveforms on both sides of this converter.b). Calculate the average power flow into the converter
if the motor is rotating in the reverse direction, with the same current draw and the same induced emf Ea value of the opposite polarity
In an electricity experiment, it was observed that as the potential difference in volts across a thin platinum wire increases the current in amperes changes as follows: (V,I)=(0,0), (1.0,0.112), (3.0,0.337), and (6.1,0.675).
An eight-point real-valued signal s has DFT given by S = [ 3 x1 4 -4+3j -2 x2 x3 1-2j ] A. Compute s[0] - s[1] + s[2] - s[3] + s[4] - s[5] + s[6] - s[7] using one entry of X only. B. Determine the values of x1, x2, x3.
Two loads are connected in parallel. The voltage across the loads is 8kVrms. The first load is rated at 12 kW with a 0.6 lagging power factor. The second load is rated at 20 kVA with a 0.8 lagging power factor. Find the complex power of the two lo..
a) What is the minimum bandwidth that they need b) If the carrier amplitude in the transmitter (before the power amplifier at the output) is 5V, what is the maximum signal amplitude they can permit in the transmitter without introducing distortion
A system is described by the differential equation ty'(t)-8y(t)=x(t). Classify the system as to linearity, time-invariance and stability. A system is described by the equation y(t)= \(\int_{t/3}^{-\infty}\)x( \(\lambda\)) d.
First you must give all different possible connection types for them and then, for each case, you should develop some tests that can define the connection type and calculate the current passing through the capacitors.
Find the magnitude of the electric field at all points in space both inside and outside the slab, in terms of x, the distance measured from the central plane of the slab. What is the field for x = 1.00 cm What is the field for x = 8.00 cm
draw a state diagram for an FSM with an input gcnt and three outputs x,y, and z. The xyz outputs generate a sequence called a Gray code in which exactly one of the three outputs changes from 0 to 1 or from 1 to 0.
