High Voltage Inverter

This is a simple high voltage inverter circuit. It is uses NPN transistor type 2N3055. This circuit used to invert low voltage to high voltage. Besides that, this circuit uses flyback transformer that can obtained from B/W or color TV or computer monitor. R1 (110 Ohm/5W) and R2 (27 Ohm/5W) are used to limit the […]

Super Simple Inverter

This is example of a simple inverter that can be used to power fluorescent lamp and a small strobe. This circuit will produce over 400VDC from a 12 VDC, 2.5 A power supply or marine battery or an auto. This circuit is very simple because it does not require custom transformers or coils. Also all […]

12V 40Watts (2x20Watts) Fluorescent Tube Lamp Inverter

A 40 watt fluorescent (tube lamp, TL) or two 20-watt tubes in series will be driven by this circuit. The transformer is wound on a ferrite rod 10mm dia and 8cm long. The diameters of the wire are not critical but our prototype used 0.61mm wire for the primary and 0.28mm wire for the secondary […]


12V 6-12 Watt Fluorescent Tube (Neon) Lamp Inverter

A 40 watt fluorescent tube lamp or two 20-watt tubes in series will be driven by this circuit but this circuit will produce less brightness than usual, since this circuit only deliver 6-12 Watts. This circuit draws 0.9-1.2 Amps for 2 x 20 watt tubes, or 0.45-0.9A for 1 x 20 watt tube, depending on […]


12V to 220V 100W Inverter

The following circuit  Inverter 100W, simple to use and excellent ideas. If we want to work with the electrical equipment outsite home that has a voltage 220Volt /AC 50HZ, that only have  around 100Watt not exceed.  Yo need Small power inverter around 100Watt. This inverter perform modify from work electrical power forces of electric battery […]

12/220V Converter With Sine Output

How it work : The master oscillator, a voltage reference and comparator collected on DA2. External elements DD1 and DD2 repeated internal structure of the TL494, in the part that works is unstable at low frequencies (false positive D-flip-flop). Further, using the low-pass filter suppresses the upper harmonics of the PWM. LPF consists of two […]

100W inverter 12V to 220V

To lower or raise any specific voltage is better adapted from a transformer, but this component does not operate in direct current, which is available in battery or vehicle. Therefore we must put an oscillator that generates an alternative current. The Integrated circuit (CD4047) is an oscillator that has the output inversely to one another. […]

Transistorized Inverter 60W 12V DC to 230V AC

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 […]

Inverter 12V DC to 240V DC

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 […]
