48 volt dc 12 volt dc converter circuit diagram

12v to 18v : 120 turns of 24swg wire in a 0.5mm ferrite core, and so on….6v to 12v 500mA : 60 turns of 36swg wire in a 0.5mm ferrite core.6v to 12v 1Amp : 80 turns of 24swg wire in a 0.5mm ferrite core.We are using a general purpose high current MOSFET, P55NF06 here which is mostly used in inverters.Īnd for making the inductor coil, we need to follow the below chart for some expected voltage range. In this circuit we are going to put DC pulse through an inductor and take the boosted current from the inductor when it’s off.

Like 12 Volt 3 watt model, which require 250mA current, and since we are giving 5 volt as input, we have to spend around 720mA current with 80% efficiency. We can use it for low power consuming models. This is a DC to DC step up converter, also known as boost converter and it has efficiency of 60-80%.Īs the efficiency of this circuit is not very high, so we can’t use it for large projects, which needs max power. This is based of the theory that inductor holds current and passes in opposite direction. You can use this 5V to 12V converter circuit to easily get 12 volts from a 5V similar source.
