Σύνοψη

Inverters are simply DC to AC converters in which the output it is not sinsoidal but square or quasi-square waves and for low and medium voltage applications are acceptable for for high power applications filters are used.
There are two types of inverters.
a] single phase inverters.
b] three-phase inverters.
Inverteres are widely used in industrial applications such as.
- a.c motor drive
- induction heating.
- stanby and uniterruptible power supplies.
In electrophotography inverters is of great importance due to the fact that electrophotography pictures are taken by placing a living thing in the field of a high frequency electricity and the picture produce shows the energy aura given from the living thing.
The importance of electrophotography is to explain some physical phenomenum found in our life.
The construction demand to design a rectifier and the high-frequency inverter.
The rectifier it was easy to design since it is a bridge-rectifier and for stabilezer an op-amp 741 is used.
The inverter base on the ideal that the two switching transistors must not operate simultaneously so the contro unit design offer this facility.
The oscillator output is a high frequency and the potencometer is for having a variable frequency.
The transformer used is selected from the fact that it can be used for high frequencies applications.
