The micro transformer has high measurement accuracy, which can satisfy the demand for fine measurement of current, voltage and other parameters. The micro transformer is integrated with other sensors, processors and other components to form an integrated intelligent measurement unit. The following is the analysis of the micro transformer industry in 2024.

Micro transformer industry analysis

      The "2024-2029 China Micro transformer Industry Development Trend and competitive strategy Discussion Report" pointed out that the micro transformer is a small volume, light weight, and can convert electrical energy into magnetic energy or magnetic energy into electrical energy electronic components. It is mainly used in various electronic devices, such as sensors, power supplies, audio amplifiers, magnetic storage devices, etc. The application range of micro transformers is particularly wide, from home appliances to aerospace, medical equipment, automotive and other fields have applications.

       In recent years, the micro transformer industry has benefited from the growth of global energy demand and the progress of the power industry, showing a steady growth trend. In particular, the rapid progress of renewable energy and the promotion of smart grid construction have brought broader market space and opportunities for the micro transformer industry.

       According to the data, China's output of micro transformers increased from 139 million in 2022 to 343 million in 2023, with a CAGR of 12% during the period.

       From the perspective of the industrial chain, the upstream mainly involves raw material suppliers such as steel, non-ferrous metals and insulation materials, the middle reaches are transformer manufacturers, and the downstream includes application customers in the fields of power systems, instruments and meters.

       At present, there are a large number of micro transformer manufacturers in China, and the market concentration is not high. China's micro transformer manufacturers are mainly concentrated in East China and North China, in 2023, the number of micro transformer manufacturers in East China accounted for 46.6% of the country, followed by North China, accounting for 21.3%.

Micro transformer industry trends

       Miniaturization and integration: With the continuous progress of electronic technology, the volume of miniature transformers continues to decrease. Miniaturization can not only reduce the overall size of the equipment, but also provide solutions in some application scenarios where space is limited. Integration is another trend, the micro transformer is not only a separate measurement component, it will be integrated with other electronic components to form an integrated measurement system. This integrated product can not only reduce space occupation, but also reduce production costs and improve product reliability.

       High precision and high reliability: With the popularity of industrial automation and smart grid, micro transformers have higher and higher requirements for measurement accuracy. High-precision micro transformers can provide more accurate power data, which helps to improve the operating efficiency of equipment, reduce failures and improve the stability of the system. For example, in a smart grid, accurate current and voltage measurements are critical to the operation and scheduling of the grid

       Low power consumption and long life: Low power consumption and long life are another important direction of the development of micro transformers. In particular, in application scenarios such as the Internet of Things and smart home, low-power design is particularly important because devices often need to work stably for a long time

       Intelligence and data analysis: With the progress of artificial intelligence, machine learning, big data and other technologies, the micro transformer is not only a simple sensor, its data acquisition function will be combined with intelligent analysis and decision-making system, and become an important part of the smart grid and smart equipment.

       Wireless and remote monitoring: With the popularization of Internet of Things technology, the wireless trend of micro transformers is becoming more and more obvious. Wireless communication technology (such as wi-Fi, Bluetooth, Zigbee, LoRa, etc.) allows the miniature transformer to connect wirelessly with other devices to achieve remote data transmission and mastery. This has important implications for distributed systems such as smart grids and smart cities.

       In general, with the continuous progress of smart grid, Internet of Things, industrial automation and other fields, the micro transformer industry will usher in broad opportunities for progress. Through technological innovation, intelligent progress, and industry segmentation, micro transformers will play a greater role in various high-precision measurement, monitoring and mastery systems in the future.
