24v to 12v converter schematicAs shown, the 24v to 12v converter circuit is nothing more than an integrated adjustable voltage regulator that acts on a group of power transistors in parallel. These transistors can be said to perform heavy duty while the regulator responsible for controlling them.

12v to 24v dc converterIs often you need to install some equipment in a car that works with the 24 volt source. May not be a problem for buses or trucks which have the power to work with two batteries in series. But the cars have only one battery, so it becomes necessary to raise the voltage electronically.

With this simple DC voltage converter circuit we can reduce 12v to 5v  symmetric voltage and can use existing resources.
Symmetric 12V to 5V converter
Here used 3-Terminal Adjustable Regulator LM317  for positive regulation and LM337 for the negative regulation. The maximum output current is 1A, and as always highly recommend a good heat dissipation for this IC regulator.

Car DC to DC Converter for laptops

Laptop power supply for  car

Laptops today are the what is called notebook computers, which now is becoming popular. Laptops can be brought into the bag making it suitable for business trips. And even as the “home entertainment center” laptop is more convenient, because it takes a little space. However, in my opinion, there is one very important which become shortcomings – most laptops which powered by an electric voltage of 19V, making it impossible for them to direct the power to an integrated network vehicle (12-14V). It is very important, especially when laptop battery capacity is not more than two hours in active mode. And what if you, at some object in the whole day want to process some data, but no other useful sources of electricity?
