VG15-12S250

DC DC Converters are a type of converter that transforms electrical energy from one voltage level to another without the need to rely on an alternating current (AC) source. A common type of DC DC converter that is widely used in a range of applications is the VG15-12S250. This article will take a look at the application field and working principle of the VG15-12S250.

The VG15-12S250 is a two-stage DC-DC boost converter, which is non-isolated and features a fixed 400 kHz switching frequency. It has an input voltage range of 4.5-14V, with an output voltage of up to 15V. It has a wide temperature range from -40 to +125ºC and can handle an output power of up to 250 watts.

The VG15-12S250 is suitable for a wide range of applications such as military, automotive, LED lighting, industrial instrumentation, and battery charging. In these different types of applications, it can be used to provide power for various components, such as electric motors, radio frequency generators, and LEDs.

The working principle of the converter is based on the principle of conversion of energy from one level to another. In this case, it is used to convert a low-voltage direct current into higher voltage direct current. The converter comprises of two main components – an inductor and a capacitor.

When the switch is turned on, current starts to flow through the inductor and this creates a magnetic field. As current increases, this magnetic field causes the inductor to store energy in the form of an increasing magnetic field. However, when the switch is turned off the magnetic field collapses inducing a current in the opposite direction. This produces a voltage drop across the inductor, so the voltage across the capacitor is increased.

This action continues over time, with the generated voltage increasing each time the switch is turned on and off. The output voltage is, therefore, generated from the energy stored in the inductor and then released by the capacitor when the switch is turned off. The output voltage is thus greater than the input voltage and can be adjusted using a knob or switch.

In addition to the above, the VG15-12S250 also features built-in protection against short circuits as well as overheating. This helps to ensure that the load and converter do not suffer from any damage as a result of incorrect operation or misuse.

The VG15-12S250 is a highly efficient and reliable DC-DC converter that is suitable for a wide range of applications. It is easy to install and use, making it a great choice for applications where the reliable conversion of energy from a lower to a higher voltage is required. The built-in protection features also add to its safety and ensures that it can cope with even the toughest of conditions.
