Inverter Circuit For Soldering Iron

Schematic Diagrams      Comments Off on Inverter Circuit For Soldering Iron

Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) In the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors Q1 and Q2 (each BC547) form an astable multivibrator that produces 50Hz signal. The complementary outputs from… Read more »

Voltage Inverter Using Switch-Mode Regulator

Schematic Diagrams      Comments Off on Voltage Inverter Using Switch-Mode Regulator

This circuit uses a step-up switch-mode regulator, which is usually used to produce a positive supply, to generate a regulated negative output voltage. The device used here is the MIC4680 from Micrel (http://www.micrel.com), but the idea would of course work with similar regulators from other manufacturers. Because of coil L1,… Read more »

12V Flourescent Lamp Inverter

Schematic Diagrams      Comments Off on 12V Flourescent Lamp Inverter

Fluorescent tubes use far less energy than incandescent lamps and fluorescent tubes last a great deal longer as well. Other advantages are diffuse, glare-free lighting and low heat output. For these reasons, fluorescent lighting is the natural choice in commercial and retail buildings, workshops and factories. For battery-powered lighting, fluorescent… Read more »

100W Inverter Circuit Schematic

Schematic Diagrams      Comments Off on 100W Inverter Circuit Schematic

Here is a 100 Watt inverter circuit using minimum number of components. I think it is quite difficult to make a decent one like this with further less components.Here we use CD 4047 IC from Texas Instruments for generating the 100 Hz pulses and four 2N3055 transistors for driving the… Read more »

Discrete Voltage Inverter

Schematic Diagrams      Comments Off on Discrete Voltage Inverter

The circuit in the diagram enables a negative voltage to be derived without the use of integrated circuits. Instead, it uses five n-p-n transistors that are driven by a 1 kHz (approx) TTL clock. When the clock input is high, transistors T1 and T2 link capacitor C1 to the supply… Read more »

12V Fluorescent Light Inverter

Schematic Diagrams      Comments Off on 12V Fluorescent Light Inverter

This is a low voltage 12V fluorescent inverter for powering two 20W or single 40W fluorescent tube. It’s a circuit you can put together from junk box components and is a very simple to build. The transformer is hand-wound on a ferrite rod from an old transistor radio and the… Read more »

500W Modified Sine Wave Inverter

Schematic Diagrams      Comments Off on 500W Modified Sine Wave Inverter

Here is a simple but powerful, stable and efficient schematic diagram for a 500W modified sine wave inverter circuit. Originally I used a 555 timer and a CD4017 decade counter to produce the modified sine wave, but then I thought a simple PIC micro controller with its internal clock would… Read more »
