Converting the voltage level of a device is made simple with the use of a switched-mode power supply. SMPS transformers produce usable energy outputs while helping maintain an efficient use of energy. Its purpose is to receive electricity from external power supplies, and then to convert that energy to a level of voltage demanded by a particular load. One of the most common places to find this type of power supply is in computers.
Development of SMPS Transformers
Prior to its development, the majority of personal computers were limited to linear regulators. The problem was that a significant amount of heat was generated during the regulation process, which wasted voltage SMPS power unit now produces an unvarying amount of voltage with the help of simple resistors.
SMPS transformers do not waste energy in this manner, therefore there is far less heat created in the process. Transistors and capacitors are what these transformers use to regulate voltage. The power supply has the ability to select a combination of components that provides the exact amount of voltage needed by a load. Power is saved and the load requirement is met.
SMPS Benefits
A switched-mode power supply offers several benefits. Not only is it highly efficient, but it is usually smaller and weighs less as compared to linear models. Their size also makes them less prone to overheating, and they have a longer life expectancy. Overtime, the savings add up for companies.
SMPS is a bit more complex than the older units it replaces. It also costs more to manufacture. Electromagnetic interference can also be created as a result of rapid voltage switching. However, modern power supplies can put this in check by using internal filters to limit any interference. Thus, machinery nearby is protected. The return on investment outweighs the cost.
Devices That Use SMPS
While computers are the most common devices, cell phone chargers are equipped with small units as well. They prevent the cell phones from damage when drawing current from an electrical wall unit. SMPS can be used for any application that requires high efficiency and power conversion. Without the technology, it would be impossible for devices to operate efficiently.
