First you should rectify the input ac voltage, but instead of using diode bridge, use a thyristor bridge(in diode bridge change the diodes to thyristor).
Connect the gates of the thristors together, cause they all must have the same fire angle.
On a paper calculate the dc level of the full wave signal(dc level of a full wave rectifier with thyristor is ready on your notebook or can find it on the internet by a simple search) to find the fire angle of the thyristors.
Now you can change the fire angle of the thyristors by changing the currents of the gates to get your desired dc level.
now you have a signal with your desired dc level, then smooth the output by a capacitor.

∙ 14y agoYes, but the current load rating will need to remain the same, meaning you will derate the transformer significantly.
For example, if I have a 220 volt, 1kVA rated single phase transformer, at 220 volts it is rated for 4.5 amps of current. You CANNOT push more than 4.5 amps through it without incurring damage due to excessive heating no matter the voltage applied. So you can run at 12 volts, but it's rating will change to 54VA.
Also, depending on the transformer design, the output waveform may be nonideal (include lots of harmonics) with only 12 volts applied.

The total resistance of a parallel circuit is 25 ohm's if the total current is 100 milliamps how much current is through a 220 ohm resistor that makes up part of the parallel circuit?
The equation for parallel circuit is: 1 / X = 1/R1 + 1/R2 + ... + 1/RN Plug in the known resistances: 1 / 25 = 1 / 220 + 1 / X Solve for X: 1 / 25 - 1 / 220 = 1 / X 8.8 / 220 - 1 / 220 = 1 / X 7.8 / 220 = 1 / X X = 220 / 7.8 X = 28.20512821
Will using a transformer to convert 230V to 12V DC consume more energy than using a few capacitors and resistors without a transformer?
no, the transformer is much more efficient <><><> HOWEVER- a transformer only changes the voltage of AC current- it does not change it to DC. You will still need diodes or rectifiers. You can also use a motor/generator- a 230v AC motor turns a 12 v DC generator.
Is it safe to run a 220 volt AC to 12 volt DC step down transformer in a 110 volt outlet and will it transform it to 6 volts or will it run at 12 volts?
Since there is an AC to DC converter in there, it's hard to say. If it's a basic transformer to rectifier to capacitor design it will put out 6 volts. If it is a transformer to a voltage regulator it's hard to say what will happen. Certainly the drive voltage to the regularor will be cut in half. It may or may not run, but won't be able to run at 12 volts because there won't be any 12 volts to drive the regulator. (There will only be 6 volts.) If it is a switcher it may work fine or it may do nothing.
Can a transformer increase the 12 volt of electric charge into desirable voltage?
A transformer can change any AC voltage to any other AC voltage. But if you put DC into a transformer, the main component at the output is smoke. Furthermore, sir, you have insulted 12 volts by implying that it is undesirable.
How do you convert a 12-0-12 volt transformer to 16-0 volts transformer?
You can not convert the transformer without cutting the secondary windings. The secondary winding is a split secondary that is wound that way from the manufacturer. To accomplish what you asked would entail unwinding each side of the 12 volt winding half way. At this point solder a pigtail out to a terminal block. This would be your 6 volt tap. Then the coil would have to be rewound to its original state as before the unwind. This same procedure will then be done to the other side of the secondary. Done as a project, maybe, workable within ones capabilities, no.

Can you put 220 volts onto a 110 to 12 volt transformer from the US?
No you shouldn't. Doubling the voltage will double the current through the device. This in your case will apply 24volt to the device connected to the downconverter and will burn it out.
Can you use a step up transformer on a 110 and safely power a cooktop that requires 220?
Generally,no, you can't. Most 110-volt outlets provide only a limited amount of current, normally in the range of 15 amps (maximum). In that case, the maximum power output of the outlet is about 1800 watts. Most 220-volt cooktops I've seen require twice to four time that amount of power, with some power requirements reaching 12 kilowatts (12 kw or 12,000 watts). But these large power users are mostly 36" induction cooktops.In the case of attempting to operate a 220-volt cooktop on an "standard" 110-volt electrical with a stepup transformer, the outlets you have could not begin to provide the required power. If you do the math, you'll find that even attempting this is a very bad idea. Consult an electrician for conformation. No professional electrician would even submit a bid to you to do this job (powering a 220-volt cooktop from a 110-volt circuit with a stepup transformer). They'd tell you over the phone that it isn't something that will fly past the electrical code.

Does a 600 watt garden lights transformer pull 600 watts all the time or just the load from the lights you have on it?
Watts are power. If the lights were mostly or totally switched off, you'd have a circuit generating 600W of heat somewhere if the transformer still took 600W, not only that, but when you switched on, the 600W that the transformer was consuming, would not disappear, so the total drain would be 1.2kW. ---- Don't understand the above answer. The 600 watts on the transformer nameplate is the maximum amount of wattage that the transformer can produce and still be within its safety limits. It doesn't draw that wattage all the time. If you had two 50 watt lamps connected to the transformer then the transformer has the capacity of 500 watts left. The transformer will only produce the wattage that the load requests. The transformer has the ability to supply twelve 50 watt bulbs. 12 x 50 = 600. Any more bulbs than 12 and the transformer is in an overload condition.
The insulation resistance of a transformer winding can be easily measured with?
It depends on the rated voltage of the transformer winding -are you talking about a 12-V transformer winding or a 400-kV transformer winding? Obviously, there is no one answer to your question!
