Suitable heatsinks may be used for the output stage transistors. Somewhat higher wattage can be achieved by increasing the drive to 2N3055 transistors (by lowering the value of resistors R7 and R8 while increasing their wattage). This voltage can be used to heat your small electronic devices such as lamp, soldering iron, battery charger etc. Transistors Q1 and Q2 (each BC547) form an astable multivibrator that produces 50Hz signal. It uses eight transistors and a few resistors and capacitors.

When you power the circuit using switch S1, transformer X1 produces 230V AC at its primary terminal. Description Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) In the absence of mains supply. The centre-tapped terminal of the secondary of the transformer is connected to the battery (12V, 7Ah), while the other two terminals of the secondary are connected to the collectors of power transistors T7 and T8, respectively. In a homemade inverter circuit using 2n3055 transistors, what can improve the output.

The outputs from the drivers are fed to transistors T5 and T8 (2N3055) connected for push-pull operation.Ī 230V AC primary to 12V-0-12V, 4.5A secondary transformer (X1) is used. In the simplest form, all we need to convert a DC supply into AC.

The complementary outputs from collectors of transistors T1 and T2 are given to PNP darlington driver stages formed by transistor pairs T3-T4 and T6-T7 (utilising transistors BD140 and 2N6107). For obtaining correct frequency, the values of resistors R3 and R4 may have to be changed after testing. Transistors T1 and T2 (BC548) form a 50Hz multivibrator.
