How to get an alternating voltage of 220 V from a 12 volt battery
With this device, you can get an alternating voltage of 220 V from a 12 volt battery. His scheme is published in the Bulgarian magazine "Mlad Designer." The basis of it is a multivibrator on transistors VT 3? VT4? Operates at a frequency of 50 Hz. On transistors VT1, VT2 and VT5, VT6 powerful amplifiers are loaded, loaded on a matching transformer T1 of 100 W power. Its secondary winding is designed for 220 V and 0.5 A, two primary windings - each 10 V and 10 A. The converter can supply electric lamps, soldering irons, coffee makers and other electrical appliances for which the rectangular shape of the voltage does not matter. The device can serve as an emergency source of mains voltage. The semiconductor devices indicated on the diagram can be replaced by domestic ones: VD1 / VD2 - KD213, VT5 - KT814, KT816, VT3? VT4 - KT 315, KT312 with any letter indices.
