The converter provides the necessary power required within the car and helps to power the on-board computers. It is also used in applications which require high power ranging from 10 watts up to 250 watts.

Working Principle

The V48B12E250B2 converter works on the principle of step down conversion where a high voltage is stepped down to the required voltage, in order to match a particular application\'s requirement. It works on the basis of a combination of buck and boost converters, and is based on a 6 switch control scheme.

The buck converter works on the principle of voltage transformation, where the controller of the converter is used to take the input voltage and divide it down to the desired output voltage. The boost converter is used to step up the voltage from the input source, to the desired voltage which is then supplied to the application.

In the V48B12E250B2 converter, the two converters, buck and boost, work in parallel with the help of a 6-switch control system. The 6-switch controller helps in regulating the current and voltage within the converter, and also performs safety functions such as over-current and voltage protection.
