Transformers - how do they change an AC current to a DC current?

Or vice versa. I know that the number of coils either increases or decreases the voltage, but the AC to DC, or DC to AC, thing has me puzzled.Transformers - how do they change an AC current to a DC current?AC to DC is easy, you bring down the voltage with a transformer, and you rectify the current with Diodes, mostly a diode bridge which is a collection of 4 diodes to split the Negative from the Positive current. A Capacitor will than sit between the Positive and the Negative to flatten the current to DC which is like a straight line of current, unlike the AC which is like waves.



DC to AC requires the opposite conversion which is more complicated, to make a straight line current (DC) into Waves current (AC) and then use a transformer to increase it from say an originally car battery power of 12V now modified to AC and into to 230 V AC for normal use.



AC to DC usually provides more amps on DC while to go DC to AC provides less Amps on the AC than what it pulls from the battery in DC.



Hope this clarifies things a bit better.Transformers - how do they change an AC current to a DC current?
I'm not sure how they change voltage, but it's the clever way they're put together that let's them change from aeroplanes to cars to motorbikes.

Peace and love throughout your life from a retro cartoon fanTransformers - how do they change an AC current to a DC current?That is because transformers do nothing to change from AC to DC. A rectifier is needed, most often a full-wave bridge rectifier is used. To go from DC to AC requires a 'chopper' or inverter.Transformers - how do they change an AC current to a DC current?
Ac to dc is changed using a diode or a group of diodes called a rectifier , i think.Transformers - how do they change an AC current to a DC current?They don't. You need a rectifier for that. It's a circuit with diodes in it. Check the link.Transformers - how do they change an AC current to a DC current?
They don't. Transformers only change voltage, you need extra circuitry to change AC to DC.
Not the transformer, but rather a rectifier.
