In life of human who is fond of electronics quite often there is a task to transform alternating current to constant. Generally, quite simple task for skilled, in this sphere, the person. But what to do if you are only a beginner in electronics? There is a number of devices which will help us with it
It is required to you
- Source of alternating current, conductors, diode bridge, consumer of a direct current.
Instruction
1. For a start we need to understand what is electric current and what alternating current differs from constant in. The ordered movement of charged particles is called electric current. In direct electric current through the section of the conductor for identical intervals of time there passes the identical amount of charged particles. And here in alternating current quantity of these particles for identical intervals of time always a miscellaneous.
2. And now it is possible to break directly to transformation of alternating current to constant, with it we will be helped by the device under the name "diode bridge". Diodny Bridge or the bridge scheme - one of the most widespread devices for straightening of alternating current. Initially it was developed with application of radio tubes, but was considered as difficult and expensive solution, instead of it more primitive scheme with a dual secondary winding in the transformer feeding the rectifier was applied. Now, when semiconductors are very cheap, bridge scheme is in most cases applied. But use of this scheme does not guarantee 100% of straightening of current therefore in the scheme it is possible to add with the filter on the condenser and also, perhaps, a throttle and the voltage stabilizer. Now, at the release of our scheme as result we receive a direct current
