3/5 VCD to activate 12 VDC VALVE

$30-250 USD

$30-250 USD

Paid on delivery
From PIC Atmel328P battery powered with a maximum capacity of 4.5V and a minimum of 3.5V I have to operate a 12VDC valve. I have to charge a 4700uF electrolytic capacitor and then operate the valve with relays. At the moment I made a charge pump but it is very slow, it takes 2 minutes to bring the voltage to 12 volts from 3.5 volts. Anyone have a more efficient solution?

Hello, Your charge pump need to be re-designed to allow higher levels of energy to pass through. A more energy-efficient option is to supply your system with 12VDC. Regards

Hi, we did this before to get 150v from 12v, it is simple way, you can use boost converter or transformer if high voltage We can build and show you a video of working system.
