Transistor DC-AC inverter capacity

!±8± Transistor DC-AC inverter capacity

This video shows a DC-AC inverter, which has an output voltage regulatet, and there is no IC is used. The 50 Hz square wave is generated by a 2-transistor oscillator. The 50 Hz square wave is then obtained by the driver transistors, the "guide" of the bridge complete two two TIP122 TIP127 Darlington transistor exists. Thus armed, the bridge passes the full power transformer and alters the polarity - the results of AC and the AC has been strengthenedthrough the transformer. The voltage regulation system mainly consists of a voltage divider and a transistor that "pre-biased" and then gets a negative voltage from the voltage divider. The NPN transistor then amplifies the difference between these stresses and leads to the PNP transistor TIP127, which is reliable, especially for the power that is fed into the transformer. This inverter is not a good efficiency. The transistors get very hot after a few minutes to run the CD-Radio,I have shown. In addition, the input voltage must be at least 6V highest voltage of the transformer ... With a transformer with 18V and 24V input inverter have been able to feed a 230V 40W bulb in its normal brightness, but the pear was "flicker", so do not know if it came from the power supply or inverter. This project is more of a "proof of concept" project that I did, but I soon as the pattern of the converter can be installed again if you want to share. The frequency is...
