Why can an inductor make the current passing through it smaller?

Power inductors are inductors used in power circuits such as DC-DC converters, which are also known as power coils, power chokes, etc. The inductor has the capability of accumulating energy through self-induction, and the DC-DC converter of the chopper circuit converts the voltage by cooperating with the inductor and the switching device. It is an inductor for power supplies and circuits, made of a metal composite or ferrite material. It is mainly used in circuits that convert a specific voltage to the required voltage and provide a stable power supply for the IC. Since an inductor is used in a power supply circuit, it is manufactured to maintain inductance when a current is applied and to have a low resistance characteristic

A coil is a general term for a spiral electrode. Among them, coils used for electrical purposes are called inductors, and can be divided into two categories, one is RF inductors for signal systems, and the other is power inductors for power systems. The power inductor described in this paragraph is a component that forms part of a voltage conversion circuit such as a DC-DC converter.

According to APO statistics and forecasts, the global metal power inductor market sales reached $3.7 billion in 2022 and is expected to reach $5.6 billion in 2029, with a compound annual growth rate (CAGR) of 6.6% (2023-2029). At the regional level, the Chinese market has changed rapidly in the past few years, the market size in 2020 is 1193.4 million US dollars, accounting for about 35.9% of the global market, is expected to reach 2139.2 million US dollars in 2027, when the global share will reach 40.1%

With the mobile phone and other electronic products to thin and short, functional integration as the appeal, in the case of limited packaging space, in the face of the rapidly increasing number of components, the size of the inductor used is also greatly reduced. With the rapid deployment and application of the new generation of information technology, the demand for applications such as the Internet of Things, consumer electronics -TWS headphones, GPS+ Beidou has erupted, and communication products have been developed towards high-frequency, broadband and high transmission volume. The environmental requirements of low-voltage and high-current chip and low-power products inevitably require peripheral components to have low DC resistance and high current resistance. In the past two years, the United States has continuously put pressure on China, which has caused certain obstacles to the development of China's industry, but also accelerated the pace of domestic self-sufficiency, when the demand exceeds supply, domestic enterprises will accelerate their research and development, improve product performance, reduce costs, etc., will further promote the development of domestic metal power inductors Metal power inductors market participants. The quality is uneven, the price gap is also large, some large companies produce products in the market competitiveness is very strong, through long-term development and accumulation has formed a strong technical advantage and good cost control structure, the implementation of customized products has also improved the competitiveness of enterprises, causing challenges to some new participants, it is expected that with technological progress and capacity improvement, Some domestic manufacturers will also flourish "2023-2029 global and Chinese metal power inductors market: The report is APO Research's report on the global and Chinese metal power Inductors market, examining past as well as current growth trends and opportunities to gain valuable insights into the market indicators for the forecast period 2023 to 2029.
