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…)
