Power Supply Splitter 9V to ± 5V

Power Supply Splitter 9V to ± 5V
This power supply splitter circuit can divide the voltage of ± 5V only from a 9V battery. This circuit consists of three ICs. The first is IC ICL7660, these are monolithic, CMOS switched-capacitor voltage converters that invert, double, divide, or multiply a positive input voltage. Next is ICL7663 IC a positive voltage regulator. And the last ICL7664 for negative voltage regulator. (more…)

DC to DC Converter 12V to ± 38V

DC to DC Converter 12V to ± 38V
The core of the Car DC to DC Converter 12V to ± 38 VDC is a pulse generator built on the TL494 chip. The circuit is designed to provide power supply to Monoblock Car Amplifier TDA7294. Generator frequency can be changed by varying the resistor R3. Optionally, you can download the datasheet and find out more details on chips. (more…)

Simple Converter to Power UV Lamp

Simple Converter to Power UV Lamp
This simple converter to power UV lamp scheme is a simple converter to power the ultraviolet lamp low voltage. The power supply can be applied using the 6  batteries of 1.5V  or a power supply with an output current of at least 1 A / 8V voltage outout. (more…)

DC to DC Converter 5V to 30V

DC to DC Converter 5V to 30V
This DC to DC Converter 5V to 30V schematic will convert +5 volt input voltage to +30V voltage. Direct current is converted into an alternating generator, which built on having the characteristic hysteresis inverter with Schmitt trigger and a resonant circuit. At the rectifier output voltage is formed with a doubling of high voltage 50 V. (more…)

5 Volt to 230 Volt voltage converter

5 Volt to 230 Volt voltage converter
I found this circuit from the Russian websites, and perhaps converter circuit is interesting. This circuit can convert 5 V to 230 V. It may be bit difficult to build, because as you can see in the schematic, most semiconductor components are made by Russia. But probably with a bit of surfing you can find references part. (more…)
