DC DC Converters - The Component for Altering Voltage According to Requirements
The basic function of DC DC converters is to change the voltage of direct current.They have a lot of applications both in daily use appliances as well as hi-tech equipment.A step down Dc Dc Converter lowers voltage, while a step up system raises the voltage.
Mainly, there are three parts of a Dc Dc converter, the inductor, the inverter and the transformer.Other components may also be present in a few devices according to the requirements.
Dc to Dc converters have many uses in our everyday life.The most commonly encountered example is a phone.The power stored in a phone lessens over time, which leads to a decreased voltage.With a decreased voltage, the cell phone cannot work and thus these systems are used in cell phones to bring the voltage to the desired levels.Sometimes the circuits on electronic appliances have specific voltage requirements, which may be not the same as the voltage that comes from the power source and therefore these converters are utilized in those devices; Go to Dc To Dc Converter Circuit.
There are two kinds of Dc to Dc converters; isolated and non insolated.An isolated Dc to Dc converter acts much like a barrier between the source and the output. Other common components of an isolated Dc Dc converter are sub circuits and a voltage regulator. Every sub circuit has distinct voltage level specifications, which can be lesser or greater than the voltage supply and may also be negative sometimes. The output of these kinds of converters can be negative as well as positive and therefore, they have many medical uses. There are further two types of isolated converters - forward and flyback that are distinguished by their functioning.
Rather than an inductor, a transformer stores the energy in a flyback converter. Flyback models are generally used in appliances that need less current for example cathode ray tubes. The transformer acts primarily in transferring the energy in one step in the forward converter. This kind of Dc to Dc converter can increase as well as reduce the voltage or give a combination of the two. The car amplifiers utilize these kinds of converters to increase the voltage to get a higher output.
The second type of Dc to Dc converters, which are non-isolated converters are used for stepping up or stepping down voltage by a low ratio. Buck, boost, buck-boost, cuk and charge pump are the five different kinds of non-isolated converters, each one of these having different uses and functions.
If you wish to buy DC DC converters then you must get them from a trustworthy distributor. You can also get custom-made models from a few producers. If you think that your needs are unique then you can get these units custom made for features such as higher temperature ranges of several switching frequencies. Travelers can also use these converters to operate their home appliances in any country because the voltage provisions are distinct in different countries.
