This is low cost fully transistorised inverter circuit capable of driving medium loads of the order of 40 to 60 watts using battery of 12V, 15 Ah or higher capacity. Transistors T1 and T2 (BC548) form a 50Hz multivibrator. For obtaining correct frequency, the values of resistors R3 and R4 may have to be changed after testing. The complementary outputs from collectors of transistors T1 and T2 are given to [...]
This is inverter 12V DC to 120V AC. How much this inverter can handle the load depends the transformer. More explanation about how its work and the component list, visit this page
Here is 100 Watt Inverter 12V DC to 220V AC schematic diagram. More explanation, please visit this page
This inverter circuit can be used to power electric razors, stroboscopes and flash tubes, and small fluorescent lamps from a 12 volt car battery. In contrast to the usual feedback oscillator type of inverter, the oscillator of this inverter is separate from the output stage, which allows easy adjustment of the oscillator frequency to suit different applications. The oscillator circuit consists of a 555 timer connected as an astable multivibrator. [...]
