What type of heating is the most economical?
To prepare for the heating season in advance, it is not necessary to wait for the cold weather, and then solve everything in a hurry. The main thing to include, because the weather is so unpredictable. If you have in the apartment gas, then I am not for you compose a treatise. Close the page and go read something more is needed. I decided to reflect on "The cheapest electric heating"....
Circuit of frequency Converter for three-phase motor
In order to smoothly carry out the adjustment of the rotation shaft of the induction motor and came up with an electronic device of Altivar or a frequency Converter for three-phase motor. This device operates in AC circuits. Usually adjusting the shaft speed as a function V/f, but this is a simple device, and more sophisticated devices is quite real work vector law. Frequency converters sometimes referred to as "inverters"....
Frequency Converter
Where basically apply frequency converters? Technical aspects of the use of converters. Most drives uses asynchronous motor. At this stage of development of the electronics of the frequency Converter is almost the main unit to manage this type of machines, it is more convenient to use the inverter with PWM control to change the operation modes of the motor than anything else....
The Power of three-phase inverter single-phase network
There Are cases in manufacturing power tools and equipment accounts from a single-phase voltage source. It basically realize of course you can, but remember that in this case we need to select the frequency drive in tandem with the engine, because the output tog under load should not be the largest of more than 50% of nominal....

All about that there is best in the world of the electronics!
