Repeat Prob. 3.99 for a full-wave bridge rectifier circuit. Draw the circuit.
Problem 3.99
A 3.3-V, 30-A dc power supply is to be designed with a ripple of less than 2.5 percent. Assume that a half-wave rectifier circuit (60 Hz) with a capacitor filter is used.
(a) What is the size of the filter capacitor C?
(b) What is the PIV rating for the diode?
(c) What is the rms value of the transformer voltage needed for the rectifier?
(d) What is the value of the peak repetitive diode current in the diode?
(e) What is the surge current at t = 0+?
What does "transfer function" of a filter represent What do the Amplitude Ratio (Gain) and Phase Angle represent What are the key differences between a real filter (the RC circuit) and an Ideal Filter (please read LPF Treated as an Ideal Filter)
A priority decimal-to-BCD encoder has active-LOW inputs andoutputs. If there are LOWs only on decimal inputs 2, 5, and 8, what BCD code appears on the outputs
(a) Draw the equivalent circuit. (b) Determine the ohmic value of the impedances. (c) Calculate the source current in amperes and in percent if the generator operating voltage is 3.8 kV (line-to-line) and a reactance of X=125% is connected in seri..
A point charge Q is located at (0,0,d) above an infiniteconducting plane that lies in the xy-plane and is maintained atground potential. Find a) the surface charge density as a functionof x and y on the conducting plane
A BC has CR of 15:1 with a high temperature of 1.6x10^3 K and the inlet at 290 K, 10^5 Pa. Use cold air properties and find the specific heat addition and specific net work output.
Should managers inform employees that their Web behavior is being monitored? Or should managers monitor secretly? Why or why not?
Even if a man shows no visible perspiration he still evaporates about 500 grams of water per day from his lungs. How many calories of heat are removed by this evaporation? What is the rate of heat loss in watts due to this process?
50 kmol per hour of air is compressed from p1 = 1.2 bar to P2 = 6.0 bar in a steady-flow compressor. Delivered mechanical power is 98.8KW. Temperature and velocities are: T1= 300K T2= 520K u1= 10m s^-1 u2= 3.5m s^-1
