Transistor inverter circuit 6

This is a transistor inverter circuit diagram rated for 100 watts, designed as an easy-to-build circuit. It utilizes only transistors and does not incorporate any integrated circuits. The circuit converts a 12V battery input to a 220V, 50Hz square wave signal. It employs two BC558 transistors, which, when assembled with resistors and capacitors, generate a frequency of 100Hz. Further, two additional BC558 transistors are included to divide the frequency, resulting in a final output of 50Hz. The circuit also includes BD139 and 2N3055 transistors configured as Darlington pairs to drive a 12V center-tapped transformer, stepping up the voltage to 220V at 50Hz for practical use. The inverter's central component is the CMOS 4047, which converts the 12V DC input into a 220V AC output. The 4047 operates as an astable multivibrator, producing a symmetrical rectangular signal at pins 10 and 11. This signal is amplified by two Darlington transistors (T1 and T2) before reaching the secondary coil of a transformer (2 x 10V/60VA). The primary coil produces a 220V AC output. For optimal performance, a toroidal core transformer is recommended to minimize losses. The output frequency can be adjusted using a potentiometer (P1) within a range of 50 to 400Hz. This mini power inverter employs SCRs as primary components, functioning as an oscillator generator to produce a 400Hz output at 300V with a 12V input and a current draw of 0.8A. However, a potential drawback is the risk of the circuit latching in a conducting state under heavy load or short-circuit conditions, necessitating input protection such as a fuse. The transformer used is a 10W mains type with 6V+6V windings on the SCR side and 110V+110V windings in series at the output. The inverter operates with an efficiency of 50%, with an ideal load equivalent to a 22kΩ resistor rated at 5W. The output waveform is approximately sinusoidal at a frequency of 400Hz. Additionally, a simple high-power inverter circuit using four 2N3055 transistors is described, designed for straightforward assembly as an oscillator multivibrator to drive a transformer output of 110V from a 12V battery. This design, while simple, is effective and may appeal to those who prefer uncomplicated circuits. Other related circuits include a simple MOSFET AC power inverter using the CD4001 integrated digital circuit for pulse oscillator generation, producing an output of 110V or 220V from a 12V battery. A variable resistor (VR1) is used to fine-tune the oscillator frequency. Another basic AC inverter circuit utilizes a popular 555 IC to generate frequency, which is amplified with NPN and PNP transistors (TIP41 and TIP42) to drive a transformer, yielding an output voltage of approximately 120V to 230V at 50Hz. A resistor (R4) is employed to control the frequency, and a supply voltage between 5V and 15V is recommended. This circuit is suitable for driving fluorescent lamps and can serve as a general high-voltage source for various applications. It is a cost-effective project designed for 20 to 40-watt fluorescent tubes and can be assembled using commonly available components or kits, requiring no printed circuit board. This is an electronic choke designed for conventional fluorescent lamps.

The described inverter circuits leverage various transistor types and configurations to achieve efficient voltage conversion from low DC levels to high AC outputs. The use of components such as the CMOS 4047 and SCRs enhances the circuit's functionality, allowing for frequency modulation and improved performance. The incorporation of toroidal transformers further optimizes efficiency by reducing magnetic losses, which is critical in high-frequency applications. The circuits are designed to be user-friendly, enabling hobbyists and engineers to construct them with minimal resources. Safety considerations, such as the inclusion of fuses and protective elements, are essential to prevent damage under adverse conditions. Overall, these inverter designs exemplify practical solutions for converting DC power to AC, suitable for various applications including lighting and general power supply needs.This is transistor inverter circuit diagram 100watt it sizes are easy circuit.
