Today’s handy devices are compound systems. These go on to insert more and more functions that need numerous supply electrical energy levels. The DC-DC switching converters are a key component that is used in multiple applications, including portable devices. In this article, I am going to explain to you the different types of a DC-DC converter.

DC to DC converter (which is also known as a boost converter or voltage converter) is a class of power supply that converters a source of direct current from one voltage to another. There are two types of the boost converter, one is switched and another is linear. This converter uses a voltage to regulate and create a given output voltage. The switched-mode boost converter stores the input energy periodically and releases that energy to the output at a different voltage. The storage can be in either a component like a transformer or in a component such as a capacitor.

Transformer-based converters provide isolation between the input and the output. This is the benefits of using a non-isolated industrial DC-DC converter. The DC power supply is used in most of the appliances where a constant voltage is required. The charge carries the DC supply in a single direction. Batteries and solar cells are the solar cells of the DC supply. The DC voltage can produce a certain amount of constant electricity. This converter takes the voltage from a DC source and converts a voltage of supply into another DC voltage level. This is commonly used as portable DVD players and portable chargers.

A number of devices require a certain quantity of power to run the machine. In excess of power can demolish the tool or a smaller amount of power may not be capable to run the piece of equipment. The converter takes the power from the battery and it cuts down the voltage level. The converter takes the power from the battery and cuts down the energy level. It is also necessary to step down the power of a large battery to run portable devices. In this article, I am going to show you the types of railway DC-DC converters. After knowing these types, choose the right one.


  • Switching converter:

Switched mode converter offers a few advantages. The conversion efficiency is much higher. As the switching frequency is higher, the components are smaller. The energy stored in a switching regulator can be transformed to output voltages that can be smaller than the input or greater than the output. It can carefully regulate the energy transfer and maintain a constant output within normal operating conditions.

  • Linear converter :

Unlike a switching converter, the linear converter can only generate a voltage that is lower than the input voltage. There are many advantages of an industrial DC-DC converter. The modern switching-mode controller makes the control task easy. It provides low noise and its simplicity can sometimes offer a less expensive solution.

  • Non-isolated boost converter:

The switching converter is a circuit that uses a power switch, an inductor, and a capacitor to transfer the energy from the input to the output. These can be arranged in a variety of ways.

  • Buck converter:

In the buck converter, the output voltage depends on the input voltage. This converter efficiently converts a high voltage to a low voltage efficiently. Efficient power converter reduces heat and extends battery life. This converter can be used in lots of cool applications.

  • Boost converter:

The boost converter uses the same number of components but arranged to step-up the input voltage so that the output is higher than the input.

  • Buck-boost converter:

The typical buck-boost converter allows the input DC voltage to be either stepped-up to stepped down. Isolated boost converter:

There are two main types of isolating boost converters.  In both of these types, the transformer provides the isolation between the input and the output. The transformer is used in a traditional manner to transfer energy when the switch is closed. The complexity of the converter is reduced now-days. The present invention is especially applicable in the renewable energies and industrial sector. In this sector, a particular converter can control the voltage level. 

Bottom Line:

This is all about the types of DC-DC converter that works with industrial and railway applications. It offers a mixture of features that are useful in high voltage and high-efficiency applications. It has the adjustable current capabilities and wide input range that makes this converter. This is an easy fit in demanding applications.
