This thesis project is considered Uninterruptable power-massacre.
The device is designed for continuous operation on-load capacity of 6 kVA in case of loss of mains voltage or the output of the last of tolerance, such as:
- Undervoltage in the case of inclusion in the same network as the Protective-schae6moe uninterruptible power supply (UPS) unit is powerful consumers;
- Increase in voltage in the case of reverse considered (i.e. when powerful consumers disabled);
- Harmonic distortion;
- The frequency deviation (limit is 49-51 Hz).
In any of these cases, the load will be supplied with pure sinusoidal nym 220V (ideally).
UPS can be used by both industry and households. In general, wherever periodic problems with the quality of the supply network.
Graduation project includes the following documents:-tional explanatory note drawing the block diagram, functional diagrams, received fundamentally-scheme of the general form, the algorithm works (2 sheets). Explanatory Note includes 26 figures, 33 tables, 2 applications.
