What Is Full Form of SMPS
The complete Full Form of SMPS is Switched Mode Power Supply, also known as Switching Mode Power Supply. SMPS is an electronic power supply system that uses a switching regulator to transfer electrical power effectively. It is a PSU (power supply unit) and is usually used in computers to change the voltage to the appropriate range for the computer.
SMPS has many benefits over traditional linear power supplies, including smaller size, higher efficiency, and better thermal performance. In addition, because SMPS doesn’t generate any noise or RF interference, they are often used in applications where clean power is required, such as medical equipment and laboratory instruments. While there are some disadvantages to using SMPS (such as increased cost).
Working principles of SMPS
The SMPS device uses switching regulators to turn the load current on and off to maintain and regulate the voltage output. The most suitable power generation for a system is the mean voltage between off and on. Unlike the linear power supply, the SMPS carry transistor switches among low dissipation, full-on and full-off phases and spend much less time in high dissipation cycles, decreasing depleted strength.
The working principle of SMPS can be explained with the help of an analogy. Consider a water tank with a tap at its base through which water can flow out. To maintain a constant water level in the tank, we need to keep opening and closing the tap as per the requirement.
Benefits of SMPS
SMPS or switched-mode power supplies are a power supply that is becoming more and more popular in electronics today. They offer several benefits over traditional linear power supplies, making them a good choice for many applications. Some of the critical benefits of SMPS are:
2. Small Size
3. Low Weight
4. Low Noise Levels
5. Wide Operating Range
6. Modular Design
7. High Reliability
Limitations of SMPS
Though SMPS has many advantages, there are some limitations to consider. One such restriction is that SMPS cannot be used with reactive loads. Another is that they can generate a lot of electrical noise, interfering with sensitive electronic equipment. Additionally, SMPS are generally more expensive than other types of power supplies.
