charge a 48volt battery bank from 12v battery or solar panel

How to make a simple 12v dc to 48 volt dc converter simple boost converter or flyback converter (using IC-555) to charge a battery bank from 12 volt battery or solar panel.






Most of the time we need to convert a 12volt dc to 48volt dc to charge a 48 volt battery bank from 12volt battery or even solar panel. So in this post we are going to learn how to make a 12v dc to 48volt dc converter or boost convert using timer IC-555 (readily available, cheap and always will be in production) using readily available parts from market.

This 12v to 48 volt converter circuit or boost converter is a DC to DC converter using the property of intuctor to oppose the rate of change of current through it. This transformerless electronic power supply circuit uses a timer IC-555 to operate in astable mode and this transformerless electronic power supply circuit have an output frequency of around 600Hz at 58% duty cycle.

This project is similar to 12v to 48 volt converter but have more stable and regulated output .
