The aim of this project is to develop a circuit which will step up the applied DC voltage by voltage multiplier principles. A 555 timer is used in astable mode to deliver the output approximately twice the input voltage. The output from the 555 timer is given to a voltage doubler circuit to get the desired output.
This system comprises of a voltage doubler which is a combination of two capacitors and two diodes. It also contains a 555 timer which is running in astable mode. The input voltage applied is around 6 volts DC and the output voltage is around 10 volts DC. The output of 555 timer passes through a voltage doubler to get around 12v DC with 20% regulation owing to circuit parameters. Thus we get 10 volts DC approximately. The load however should be restricted to less than 5 mA as drawing higher current would result in further poor regulation causing the output voltage falling below the expected level. The output voltage can be measured with the help of a multi-meter.
Further the project can be enhanced by adding multiple stages for getting three to ten times the input voltage.
