As indicated by a report from the European Automobile Manufacturers' Association (ACEA) in May 2023, the global production of motor vehicles reached 85.4 million units in 2022, reflecting a 5.7% increase from the previous year. This growth in the automotive industry is a key driver for the AC-DC power supply adapter market.

Leading companies in the AC-DC power supply adapter market are focusing on developing technologically advanced solutions, such as remote control capabilities for managing and monitoring power supplies. Remote control enables users to operate and oversee power systems from a distance, enhancing convenience, accessibility, and efficiency. For example, in January 2024, Mornsun, a China-based electronics company, introduced the LBH300-138xx, a high-efficiency half-brick AC/DC power supply designed for telecom applications. This power supply operates across a wide input voltage range of 85-305 VAC and is engineered to perform reliably in harsh conditions, withstanding temperature extremes from -40°C to +100°C. It is equipped with robust safety features, including input under-voltage, output over-voltage, current, and short-circuit protection, ensuring both safety and reliability.

Key players in the AC-DC power supply adapter market are focusing on developing products like heatsinks to enhance power density. A heatsink is a device designed to absorb and dissipate heat from electronic components, improving thermal management and preventing overheating. For instance, in January 2023, Transphorm, a US-based semiconductor company, launched the TDAIO-TPH-ON-240W-RD, a 240W AC-to-DC power adapter reference design. This design uses a CCM Boost Power Factor Correction (PFC) and Half-Bridge LLC topology, achieving peak power efficiency of over 96% and a high power density of up to 30 W/in³. It incorporates three SuperGaN FETs (TP65H150G4PS) in a TO-220 package, known for their excellent thermal performance. The reference design is intended to speed up the development of power systems for applications like high-power density power supplies, fast chargers, IoT devices, laptops, medical equipment, and power tools.

In April 2022, Advanced Energy Industries Inc., a US-based technology company, acquired SL Power Electronics Corp. for an undisclosed amount. This acquisition is intended to help Advanced Energy expand its addressable market and strengthen its product portfolio in the industrial and medical sectors by utilizing SL Power's complementary products and established customer base. SL Power Electronics Corp. is a US-based company specializing in the design and manufacture of AC/DC power supplies.

An AC-DC power supply adapter is an electrical device tasked with transforming energy from a grid-based power source, altering it in terms of current, frequency, and voltage. Comprising components such as an enclosure, transformer, inductor, capacitor, controller IC, and printed circuit board, this adapter plays a crucial role in converting alternating current (AC) into the required direct current (DC).

There are two main types of AC-DC power supply adapters, AC-DC wall power adapters and AC-DC external plug-in power adapters. The AC-DC wall power adapter is an external power supply designed specifically to convert alternating current (AC) power from a wall outlet into direct current (DC) power. Output power ranges typically include 5w to 12w, 13w to 24w, 25w to 100w, and above 100w. These adapters find applications in diverse electronic devices such as smartphones and tablets, computers and laptops, wearable devices, home appliances, audio and video devices, medical devices, industrial equipment, telecommunication devices, among others.
