Once had a chance to ride on official Chinese truck FAW. So, nothing special, but really liked the socket 220 were in the cabin. Can connect the shaver, the lamp, soldering iron, even a small kettle. So to me it I liked that they decided to equip this device and your car.
Schematic diagram of the inverter shown in the figure. It uses ready low frequency power transformer and the output power depends mainly on this transformer. If you use a 600 watt transformer with a single network winding and powerful low-voltage winding 12+12 V, it is possible to obtain the source an output voltage of 220 V, 50 Hz, and a maximum power of about 400 watts. To power razor, soldering iron or small kettle that's enough. You can use the transformer and the greater and lesser power, respectively, and power output will be different.
The frequency of the output alternating current is configured trimming resistor R1 so so it was 50 Hz.
The output transistors is a powerful key field type transistors REF50N06. they designed for a maximum voltage of the source-drain 60 and maximum drain current 50 A. thus have the on-state resistance of 0.003 Ohms. Knowing these the parameters can be substituted for another.
Zener 1N4753A can be replaced by others at 36 V.
