Design a full wave rectifier as dc power supply with a 1kΩ load that operates from a 120Vrms, 60Hz supply through a 10 to 1 step down transformer. The capacitor is connected to parallel to the load to provide the peak to peak ripple voltage of 2% of the peak output. The diodes have 0.7V turn on voltage.A)Draw a complete rectifier circuit to design.B)Specifly the peak voltage that must appear across the transformer secondary.C) Find peak value of the rectified voltage across the load.D) Find average output voltage.E) Find required value of the filter capacitorF) Find required diode PIV rating.G) Calculate the peak diode current.
n other case Trackers have the ability to increase power generated by direct radiation by 40 %. However, the cost of installed system (including trackers) will be $2.60 million. Calculate the cost of generated electricity in the second case.
A small gasoline engine can put out 18,000 N-m/min of mechanical power. The engine is used to drive an electrical generator that is 80 percent efficient. 1 N-m = 2.78 X 10-4 W-h. Find the output of the generator in Watts.
Determining how to use the function fft to find the DFT coefficients X[k] of x[n] in Matlab. Also, how would you plot the magnitude of X[k] in Matlab?
A buck converter has an input of 6 V and an output of 1.5 V. The load resistor is 3 , the switching frequency is 400 kHz, L 5 H, and C 10 F. (a) Determine the duty ratio. (b) Determine the average, peak, and rms inductor currents.
Design an 8-bit register with 2 control inputs s1 and s0, 8 data inputs I7..I0, and 8 data outputs Q7..Q0. s1s0=00 means maintain the present value, s1s0=01 means load, and s1s0=10 means clear. s1s0=11 means to swap
To support the wheelbarrow in equilibrium, the man's hands apply a force to the handles that is directed vertically upward. Consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the pape..

A Three phase thyristor converter, VLL=460V (rms) at 60 Hz, and Ls=5mH, the firing angle "a " is 30 degrees electrical, the converter is consuming 5Kw, the DC current is assumed to be constant.
What is the voltage output resolution of a 16-bit D/A converter with a 15 volt voltage source Also, what is the analog output voltage of the D/A converter if only the MSB is on
If you have a 30 VDC - 4A power supply and need to power two 24VDC - 0.8A MFC (mass flow controller), create a circuit that divide the voltage and can handle the power.
The feedback system for the Buck circuit can be analyzed by separating DC component from small signal perturbation. The performance of the feedback can be assessed by examining the Bode plot of the loop transfer function GL(s).
