AC to DC converter
The key component in an ac/dc converter is a rectifier bridge, typical made of 4 rectifying diodes. These let current pass more easily in one direction than the other. If the two ac input wires are connected by diodes pointing toward one of the outputs and away from the other output, then the sign of the voltage between the output leads won't switch back and forth. In principle, for modest loads (devices through which the dc current flows) on the output the average dc output current will be the same as the average absolute value of the a input current. The same relation applies to the voltages. That means that if the input ac voltage is, say, 10 V (rms), the average output voltage will be 10 V * 2*sqrt(2)/pi= 9.0 V. So the rms to average dc conversion factor is 0.90.
Under very light load, the output voltage can drift up to the peak input voltage 10V*sqrt(2)= 14.1V. Depending on the application, it may be good to use capacitors to smooth out the output voltage, so it won't go up and down.
AC to DC converter |
step 1: same size of 4 diodes |
Step 1: ingredients
needed:
1)four diodes of any size
tools needed:
1)pliers
thats all you need
Step 2: information about diode
step 2: nature of diode |
diode is a electronic ingredient that
helps electricity flow in one way.
there are two leads one positive and
other negative. on the diode one one
side there is a white coloured small
band.that is the negative side of diode.
a hand drawn figure of it is given below
Step 3: the diagram of the circuit
step 3:ac to dc converter circuit diagram |
this is the drawing of the circuit.
the circuit can be made using this
diagram even easier
Step 4: the main circuit
step 4: connecting diode negative side |
firstly take the first diode and
second diode and join their
negative leads together.lets
name this negative sides.just name.
Step 5:
step 5:connecting diode positive side |
now take the 3rd and
4th diode and join their
positive sides together
as shown,lets name this
end positive end
Step 6:
step 6:connecting input terminals |
now take the four diodes.
there are two free ends one
the first and second diode
that is the two positive ends.
now join these positive ends
to the free negative ends of
the 3rd and 4th diode.like in
the picture now lets name these
ac leads
Step 7: identifiying the poles
step 7: identifiying the poles of AC to DC circuit |
the circuit is complete.the joining place that
was named ac leads are the ac input.ac electricity
are to be given through these two ends.the end
named negative side is the positive dc output that
is positive dc electricity will come out of it. and
the end named positive side is the negative dc output.that is negative dc electricity will
come out of it.so your ac to dc converter
is ready.have fun with it
