Single and three phase plan bridge rectifier

Single and three phase bridge rectifier

When we want our application to use continuous DC voltage and as the only power source we have is alternating voltage AC then the bridge rectifier will almost certainly be part of the circuit.

The input ac voltage to the bridge can be any value as long bridge and capacitor are constructed to withstand the voltage and amperage that will work.
Of course we can build the bridge rectifier with diodes independent linking them as appropriate to the project.

The three-phase bridge rectification doing better than the single-phase, for the same frequency voltage of course.

Three-phase bridge rectifier

The capacitor stabilizes the voltage but not always with satisfactory results, however, the greater capacitance value is, the better.
Always put in parallel to the output electrolytic capacitor rather simple.

Diodes

The heat of bridge by the current is a problem so bridges must be placed in a smooth surface for this purpose, heat sink abducting heat protecting diodes. In the bridge heat sink thermal we put special silicone to avoid trapping air and for spreads heat quickly.

If we stabilized voltage, voltage without variation, must be put in the output suitable stabilizer such as for up to 1.5 amps the integrated circuit 7824 to 24 volts DC or 7812 for 12 volts DC or whatever 78 ** for another voltage.
The integrated circuit LM 317 by suitable wiring can give voltage value, by means of an adjustable potentiometer, from 1.2 to 37 volts DC.
