12v to 24v converter

12v to 24v converter
Is often you need to install some equipment in a car that works with the 24 volt source. May not be a problem for buses or trucks which have the power to work with two batteries in series. But the cars have only one battery, so it becomes necessary to raise the voltage electronically. (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…)

Voltage Converter from 1.5V to 3V

Voltage Converter from 1.5V to 3V
A simple scheme to generate the inverter voltage from 1.5V to 3V can be made ​​on the basis of slightly modified the well-known multivibrator. Under these denominations in the scheme of the frequency converter is approximately 130 kHz. Inductance value can be calculated or chosen experimentally. But you can simply adjust the frequency of the converter to produce maximum output voltage. Schottky diode VD1 can be replaced by any other similar characteristics. (more…)

Step up DC / DC Converter with LT1615

Step up DC / DC Converter with LT1615
Interesting DC / DC converter Linear Technology has presented the company, this chip is the boost converters that allow you to get the maximum voltage in 34B with the input voltage from 1.2V to 15V. It comes in a compact package of 5 pin SOT23, while for work requiring minimal external circuitry. These chips can be used, for example, a high voltage for the LCD screen or for the varicap. (more…)
