This circuit is converter to use to charge DC12V from the lead-acid batteries to AC 250V for use in a car, Boats or mobile homes. There are the output power There are the sufficient power to the small electronics such as a lamp or electrical soldering iron. In circuit use only six transistors, transformer and a few electronic parts. So it is easy

to build and cheap, too. The Q3(BC549) and Q4(BC549) both are the a stable multivibrator (AMV) has output is pulse square wave from about 50 Hz. They will alternately inductor current. When Q3 induct current will have the current flows through Q2, making Q1 connects the half coil circuit of the primary transformer with the 12V drop across voltage from battery. If you use the transistor in the output section to be number: RCA 40411 will be has the current flows through the primary coil in each time is 10 amperes. To power output (Way secondary coil) is 180 watt. However, if the number 2N3055 power output will be have a 90 watt. Because transistors being used in saturation. Therefore, it must be held on a large heat sink. there is the cooling fins that size over than 100mm up and also multiple fins. And If using transformer is triodes core, it makes a smaller size. The circuit is small, because have a little device makes do no adjust to a sine wave. Thus the wave output will be a square. Which may be a result of some electrical appliances, such as, dimmer lights and electric motors, may be will not work. Because it is designed to be used with a sine wave power, and is not recommended for use with color TV and video or audio tape.
