1. UNINTERRUPTIBLE POWER SUPPLY

2. What is the ups of a wind turbine ?
Element of the domestic wind placed between the batteries and the household power circuit, the inverter's function is to convert the DC current stored and distributed by the batteries into alternating current.

3. UPS self
* The central part consists of a semiconductor bridge IGBT for connecting each of the two poles of each entry of the two poles of output through a transistor.

4. UPS mono/mono *The output of this inverter is three phase
* Usually it separates into two to supply the rectifier and bypass
*The output of this inverter is three phase
* If the UPS fails or temporary overload, the bypass connects directly use the main network.

8. Types of UPS
Sinusoidal modified wave his sign is produced by commutation, for which it can support a strong overload.
Sinusoidal pure wave possesses neither the capacity of overload, nor the efficiency of the sinusoidal modified wave.
Square wave is less effective and is used for small loads.

9. The selection for the inverter is:
* Power rating: 20% of rated power for 30 minutes or an hour. * Peak power: 3 to 10 times their rated power. * Performance: High efficiency (> 90%). * Input voltage: if D <2 kilowatts then Ue = 12 VDC * Output voltage: stable with deviations below 5% irrespective of the voltage. * Waveform: know the tolerances on the voltage and frequency of each device capable.
