Switching Mode Power Supply (SMPS), also known as switching power supply or switching voltage regulator, is a power supply device that uses switching power technology to convert electrical energy. It works by quickly switching a switching element (usually a power transistor) to adjust the output voltage. The power supply device is mainly composed of input, output, power switch, transformer, rectifier, filter, protection circuit and control circuit.

The main function of the switching mode voltage regulator is to convert the unstable DC voltage into a stable output voltage for various electronic devices. Its switching frequency is generally much higher than that of the power grid, which makes the power supply equipment have the advantages of small size, high efficiency and wide adaptation range. At the same time, the switching mode voltage regulator also has the characteristics of low noise and low heat loss, which can better protect the stability of electronic equipment.

Switching mode regulated power supply is widely used in various electronic equipment, such as communication equipment, industrial automation equipment, computers, mobile phones, television and so on. In the communication equipment, it can provide stable DC voltage to ensure the normal operation of the equipment. In the field of industrial automation, switching mode voltage regulation power supply can also provide stable power support for PLC control systems.

SCP30D15-DN  Switching mode regulated power supply

As an efficient and compact power supply, SMPS has been widely used in many fields. However, as with all technology products, it has both advantages and disadvantages.

Advantages:

High efficiency: One of the main advantages of switching mode regulated power supplies is their high efficiency. Due to the use of fast switching switch elements, the loss of energy is reduced, so it is more efficient than the traditional linear voltage regulator power supply.
Small size and light weight: Due to the use of high-frequency transformers, the volume and weight of switching mode regulated power supplies are significantly reduced, which makes it a significant advantage in portable devices and space-constrained applications.
High stability: the switching power supply adopts negative feedback control, which makes the output voltage stability better than the traditional linear voltage regulator power supply. When the load changes or the input voltage fluctuates, the switching power supply can still maintain a stable output.
Wide input range: The switching power supply has a wide input voltage range, which can adapt to different voltage inputs in a wide range, improving the applicability and flexibility of the power supply.
Cons:

Large noise: Because the switching power supply works in the high frequency switching state, it will produce large electromagnetic interference. This interference may have some impact on nearby electronic devices, so additional filtering and shielding measures are needed to reduce the noise.
High cost: The circuit design of the switching power supply is relatively complex, and the manufacturing cost is relatively high. In addition, in order to meet higher performance and stability requirements, certain sophisticated electronic devices may require more expensive materials and components, further increasing the cost.
Pollution to the power grid: The switching power supply will produce harmonic current during the working process, which may cause certain pollution to the power grid. Although modern switching power supply designs have minimized this effect, it is still a problem that needs attention.
In summary, switching mode power supply has been widely used in electronic equipment for its advantages of high efficiency, small size and high stability.
