The high-frequency transformer market size is expected to see strong growth in the next few years. It will grow to $3.11 billion in 2030 at a compound annual growth rate (CAGR) of 7.3%. The growth in the forecast period can be attributed to increasing demand for compact high-frequency transformers, rising adoption in renewable energy inverters, expansion of electric vehicle power electronics, development of high-density power supplies, growth in miniaturized consumer electronics. Major trends in the forecast period include adoption of high-efficiency power conversion designs, expansion of smart transformer monitoring solutions, integration of connected high-frequency magnetic components, advancement of automated transformer manufacturing, deployment of robotics-assisted assembly systems.

The increasing deployment of renewable energy systems is expected to drive the growth of the high-frequency transformers market going forward. Renewable energy systems are systems that convert renewable resources into electricity or other forms of energy. The adoption of renewable energy systems is rising due to the growing need to reduce carbon emissions and address climate change. High-frequency transformers are used in renewable energy systems to efficiently convert and transfer power between different voltage levels in inverters and converters. For example, in July 2024, according to the US Energy Information Administration (EIA), a US-based agency within the US Federal Statistical System, renewable energy consumption in the United States increased by 2% from 2022 to reach a record 8.2 quads in 2023. Therefore, the increasing deployment of renewable energy systems is driving the growth of the high-frequency transformers market.

Major companies in the high-frequency transformer market are strategically developing high-efficiency planar transformers to gain a competitive edge. Unlike traditional wound transformers, high-efficiency planar transformers use a flat planar core, offering higher efficiency and power density, especially in high-frequency applications. For instance, in March 2023, Bourns Inc.'s launch of the PLN0xx-ED21 Series planar transformers exemplifies this trend. With low leakage inductance and enhanced efficiency, these transformers cater to applications requiring high volumetric power density in a low-height profile design. The focus on developing innovative products like high-efficiency planar transformers reflects the industry's commitment to meeting the evolving needs of high-frequency applications.

This high-frequency transformer market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

High-frequency transformers are essential components of switching power supplies, playing a crucial role in frequency conversion circuits. These magnetic transformers provide galvanic isolation and facilitate electrical power transfer.

The main power output in high-frequency transformer is up to 50w, 51- 100w, 101- 400w, and 401w and above. Up to 50W' for high-frequency transformers signify their power capacity and the unit of power is measured in watts. In this context, it indicates that these transformers are designed to handle power levels up to 50 watts. The watt is a unit of power, and when specifying the power range of a transformer, it helps convey its capability to manage electrical power within that defined limit. These are applied in power supplies, alternative energy inverters, electronic switching devices, LED lighting, plasma generation, personal electronics, and others, which are used in verticals such as industrial, automotive, military and defense, radio frequency and telecommunications, consumer electronics, transmission and distribution, and healthcare.Asia-Pacific was the largest region in the high-frequency transformer market in 2025.
