Portable 12V to 250V Inverter Circuit

A portable 12V inverter circuit becomes very simple 250V can be designed using the following circuit diagram. 12V inverter circuit into a 250V is designed for portable use with a power supply of 12 V car battery. An astable multivibrator made T1 and T2 produces a square wave at a frequency of 50 Hz. T1 and T2 as well as exit stage propulsion system and also work in "push-pull". When a current passes T1 T3: T5 and that it involves the second transistor is connected to half a battery of 12 V secondary winding of the transformer Tr. When working T2, T6 transistor coupled with a battery of other parts of the network adapter.

How it works

If used for 40 411 RCA output stage transistors, the current through the secondary windings can be up to 10 A, delivering a power output of 180 watts. If you use a 2N3055 transistor, the output power will be around 90 watts. Because the output transistor is driven to saturation, the transistor has a very high mounted radiators. Although it has a simple construction and has high efficiency, the drawback is the output voltage square, in the absence of the regulator depends on the work: a small load, the output voltage of 250 V ac (does not work well to control engine speed, dimmer lights, televisions, appliances nose fi.)
