Cheap 12V to 220V Inverter
Even though today`s electrical appliances are increasingly often self-powered, especially the portable ones you carry around when camping or holidaying in summer, you do still sometimes need a source of 230 V AC - and while we`re about it, why not at a frequency close to that of the mains As long as the power required from such a source remains r
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 voltage, UIN, which typically is 5 V. During this process, transistor
500w Modified Sine Wave Inverter Schematic
A simple but powerful, stable and efficient schematic diagram for a 500w modified sine wave inverter circuit.

LCD Backlight Electro luminescent Inverter
There are two major types of backlights for LCDs: LEDs, which stands for light emitting diode, or EL, which stands for electroluminescent. EL backlights tend to be more efficient and have more uniform lighting than LED ones, but they require some tricky circuitry to drive. If you`ve heard of Organic LED displays, or OLEDs, that`s basically an arra
The inverter plays a vital role in Uninterrupted Power Supply (UPS). It is used to convert the direct current (DC) to alternating Current (AC) of required voltage. The basic single phase parallel inverter circuit consists of two SCRs T1 and T2, an inductor L, an output transformer and a commutating capacitor C. The output voltage and current are V
