A 12v to 48v dc dc converter is an electronic gadget which steps up low voltage into higher voltage. It has wide application in vehicles, solar, RV and off-grid. The converter allows 48-volt-powered appliances to be powered by a 12-volt battery. It also provides constant power output and shields the load connected.
This converter plays a very vital role in the modern power systems. It benefits in energy conversion, voltage regulation and efficiency. It is usable in trucks, marine applications, DIY, and renewable energy applications.
What is a DC-DC Converter?
A dc-dc converter is an electronic circuit, which transforms one direct current voltage into another. It is able to increase or reduce the voltage level. The 12v to 48v model falls in the category of boost converter. It increases the voltage of a 12 volt input up to a constant output of 48 volts. This makes it possible to use high-voltage things on low-voltage batteries without any hassle.
Working Principle of a 12v to 48v Converter
The converter uses a boost converter circuit with switches, inductors, and capacitors. The inductor stores energy when current flows. The release of the stored energy occurs at a higher voltage when the switch is open. The voltage is regulated by the regulator within the circuit. It eliminates over-voltage or under-voltage issues.
