Switching power supplies are a specialized segment within the power supply industry, known for their compact size, high efficiency, and small footprint, gradually becoming mainstream products in the sector. The downstream applications of switching power supplies are extensive, spanning industrial sectors, consumer electronics, telecommunications, and home appliances. Among these, industrial applications account for over half of the demand for switching power supplies, while the telecommunications sector holds significant potential for growth as the industry evolves and 5G technology expands.

Linear power supplies operate with their power devices in a linear state, meaning these devices are constantly active. This leads to several drawbacks, including high power consumption, low conversion efficiency, significant heat generation, and large physical size. In contrast, switching power supplies have gradually replaced linear power supplies as the mainstream category in the power supply market since the early 21st century, thanks to their advantages such as compact size, high current capacity, and superior efficiency.

The Growth Rate of the Switching Power Supply Industry's Market Size Slows Down

According to data from the China Power Supply Association, the market size of switching power supplies in 2019 was 150.30 billion yuan, with a year-on-year growth of 5.1%. ReportWatch research indicates that the compound annual growth rate of China's switching power supply industry over the next five years is approximately 2.5%. Considering the impact of the global pandemic in 2020 on the switching power supply industry and the trend of slowing growth in downstream sectors, the market size of the switching power supply industry in 2020 is projected to reach 154.06 billion yuan.

The demand for switching power supplies in the industrial sector accounts for over half of the total.

Switching power supplies are widely used in downstream applications, with industrial switching power supplies ranking first in overall industry demand, accounting for 53.94% of the total industry output. Consumer switching power supplies come in second place at 33.05%, followed by communication switching power supplies at 6.71% and PC switching power supplies at 3.30%.

The demand for switching power supplies in the industrial and communications sectors continues to grow steadily.

According to data from the China Power Supply Association, the market size of China's switching power supply industry in 2019 was 150.30 billion yuan, with the industrial sector accounting for 53.94% of downstream applications, resulting in an application scale of 81.07 billion yuan in the industrial sector. Based on the aforementioned 2020 industry market size of 154.06 billion yuan, the application scale of switching power supplies in the industrial sector for 2020 was 83.1 billion yuan.

According to data from the China Power Supply Association, the market size of China's switching power supply industry in 2019 was 150.3 billion yuan, with the communication sector accounting for 6.71% of downstream applications. Therefore, the application scale of switching power supplies in the industrial field in 2019 was 10.09 billion yuan.

Based on the aforementioned data, the market size of the switching power supply industry in 2020 was 154.06 billion yuan, leading to an application scale of 10.34 billion yuan in the industrial sector that year.
