Why does switch mode power supply eliminate linear power supply and become mainstream in the market?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.03.28
In today's digital age, electronic devices around us are becoming increasingly popular. It can be said that everyone cannot do without electronic devices, and the key to maintaining the operation of these electronic devices is the power supply. Among them, switch mode power supplies, as an efficient, small, flexible, and multifunctional power supply solution, are gradually phasing out linear power supplies and occupying an increasingly important position in the market. Why did switch mode power supplies replace linear power supplies as the mainstream in the market? There are several main reasons.



High efficiency and low power requirements

Compared to traditional linear power supplies, switch mode power supplies can provide higher energy efficiency, reduce device power consumption, not only save energy and protect the environment, but also extend the lifespan of batteries and equipment, reducing usage costs. In large-scale use, it can improve the economic benefits of enterprises.

Lightweight and miniaturization trends

The lightweight and miniaturization of electronic devices is the mainstream trend in the current market, which can improve the portability and mobility of switching power supplies, increase space utilization efficiency, and is crucial for applications with spatial constraints such as embedded systems and sensor networks. And switch mode power supplies precisely meet this requirement, with smaller volume and weight.

Multifunctionality and flexibility

The design structure of switch mode power supply allows for providing multiple output voltages and currents to meet the needs of different devices, providing manufacturers with more choices. A multifunctional and flexible device may be able to replace multiple single function devices, thereby reducing overall purchasing and maintenance costs. This is an economic advantage for both businesses and individual users. In the industrial and commercial fields, multifunctional and flexible equipment can often improve production efficiency. This type of equipment can adapt to different production needs, reduce the time for line and equipment replacement, and improve the overall efficiency of the production line.

Digital and intelligent requirements

With the improvement of digitalization and intelligence of devices, the demand for digital control and management of power supply is also increasing. Intelligence enables devices to achieve remote control and monitoring through the network. Users can remotely manage devices, perform parameter adjustments, fault diagnosis, and other operations. This is particularly important for IoT devices and remote work environments. Switching power supplies have significant advantages in this regard.

Cost effectiveness

With the maturity of switch mode power supply technology and the expansion of production scale, the variety of parts and materials has gradually reduced its manufacturing cost, making it more cost-effective. The cost-effectiveness is much higher than that of linear power supplies.

End

In this era of rapid development of electronic technology, choosing a power supply suitable for various application scenarios is crucial. Switching power supplies are becoming increasingly common due to their high efficiency, small size, and flexibility. Whether it's your smartphone, your home appliances, or industrial equipment, they are likely all inseparable from this advanced power technology. For the performance and lifespan of electronic devices, choosing high-quality switching power supplies will be the key to ensuring their stable operation and long-term reliability.
