What Blue said holds for 1KW as well, never mind 10KW. 1.8KW is pretty much the limit of your 220V 10A home circuit. 10-20KW is your whole house service.i am sory !!!
i meant 10 KW
Don't you mean 2.2kW?1.8KW is pretty much the limit of your 220V 10A home circuit.
A ferroresonant transformer's output voltage depends upon the frequency. If the frequency varies as well as the input voltage (such as from an small engine driven generator), it's not a good solution.You can buy AC voltage stabilisers, a ferroresonant transformer springs to mind.
not once you have hung electronics off of it to regulate it. Power lines are rated by RMS current and if you are hanging caps off of rectifier bridges your peak currents cause your available AC to be around 30% down.You can buy AC voltage stabilisers, a ferroresonant transformer springs to mind.
A variac can be used to adjust the voltage, it's not regulated but adding a servo motor and controller can make it regulated which is your best bet if you want a regulated 0 to 220VAC power supply.
Don't you mean 2.2kW?
if he actually is third world, he is asking for more than a city block!Sounds like this person wants to be assured of clean AC mains. Are the feed lines that noisy that stable regulation and minimum ripple cannot be achieved?
huh? line transformers often have multiple taps to compensate for low or high line levels. While it would not be regulation, it might be sufficient for his actual needs.How are you going to short the primaries of the transformers quickly enough without shorting the mains?
If you don't short the primary you'll get a high voltage on it.
If you make before break then you'll short across the mains.
