In Industry 4.0 Driven by the dual drive of whole-house intelligence, ACDC converters, as the core carrier of power conversion, are achieving full coverage from highly reliable power supply in industrial scenarios to efficient adaptation in smart home scenarios. It meets "industrial-grade high stability" through technology iteration With the differentiated demand for "home-level miniaturization", it has become a power supply bridge connecting industrial upgrading and consumption upgrading, laying a solid foundation for the power consumption of equipment in all scenarios from factory production lines to family life.

1. Core requirements of dual scenarios: differentiation drives the differentiation of technology paths

Industrial automation and smart homes have completely different requirements for power supply reliability, efficiency, volume, and compatibility, forcing ACDC converters to form a "professional + customized" technical solution matrix.

4. Built-in overvoltage/overcurrent/overtemperature protection, in line with household safety standards. Power density ≥3W/cm³; standby power consumption ≤0.1W; supports mainstream smart home communication protocols; passes CCC/UL Home safety certification

2. Core of technology upgrade: three major breakthroughs to achieve full-scenario adaptation

In response to the dual needs of industry and home, ACDC converters achieve technological breakthroughs in the three dimensions of device selection, topology design, and intelligent control, and bridge the gap between "industrial-level reliability" and "home-level economy" barriers.

1. Wide bandgap semiconductor grading application: accurately matching scene requirements

Industrial scenario: SiC devices are the mainstream choice because of their high temperature resistance, low conduction loss, and impact resistance, which are perfectly adapted to the harsh working conditions of industrial equipment. For example, 1200V SiC The module can reduce switching loss by 70% in the ACDC converter of the servo drive, while meeting the -40°C low temperature start-up requirements.

Home scenario: GaN devices have become the first choice in the mid- to low-power segment. The MHz-level operating frequency greatly compresses the size of magnetic components, allowing products such as chargers and smart sockets to be "compact." For example, 650V GaN The solution is a 65W smart fast charging head, which reduces the size by 50% and reaches a peak efficiency of 96.5%.

2. Targeted optimization of topology architecture: taking into account both efficiency and stability

Industrial side: The totem pole PFC+LLC resonant topology is adopted to achieve high efficiency within the full load range, while reducing EMI interference, adapting to the complex electromagnetic environment of multiple parallel devices in industrial sites, and ensuring PLC, sensors and other precision equipment operate stably.

Home side: Use flyback + synchronous rectification topology to simplify circuit design and reduce costs while ensuring efficiency, while optimizing light load mode to meet stringent standards for home appliances' standby power consumption.

3. Deep integration of intelligent control: from passive power supply to active management

Intelligent management and control of industrial scenes: integrated RS485 / The Ethernet communication interface supports linkage with industrial control systems (SCADA) to achieve remote monitoring, fault warning, and dynamic power adjustment. For example, in automated production lines, ACDC converters can adjust output power in real time according to changes in equipment load, reducing overall energy consumption. 10%~15%.

Intelligent linkage of home scenes: built-in Internet of Things module, connected to the smart home central control system, supporting "peak and valley electricity price charging", "remote power on and off" and "equipment status monitoring" and other functions. For example, the ACDC converter equipped with a smart refrigerator can automatically store energy during low periods of the power grid and switch to energy storage for power supply during peak periods, reducing users' electricity costs.

3. Market structure: Domestic substitution is accelerating, and scenario-based companies are rising

Rapid growth in market size: Benefiting from the increasing penetration rate of industrial automation and the popularity of smart homes, the global industrial + household ACDC converter market size is expected to exceed 500 in 2026 billion, with a compound annual growth rate of 18%. Among them, the industrial market accounts for about 60%, and the household market is growing faster, with a compound annual growth rate of over 25%.

The process of domestic substitution is accelerating: Domestic companies such as Chippeng Micro, Silan Micro, Ming Micro Electronics, etc., have gradually broken the monopoly of international brands with their technological breakthroughs in industrial-grade power devices and home-grade intelligent control. 2026 In 2019, the localization rate of domestic ACDC converters in industrial scenarios is expected to reach 55%, and the localization rate in home scenarios exceeds 70%.

The focus of competition shifts to scenario-based solutions: leading companies shift from single product supply to "scenario-based solutions", such as providing "ACDC converters + servo drives + energy management" for auto parts production lines The integrated solution provides "unified power supply + protocol compatibility + energy consumption monitoring" packaged services for the whole house intelligence.

4. Enterprise layout strategy: two-track parallel approach to build strong barriers to competition

Dual-track technology research and development: We have set up dedicated R&D lines for the two major scenarios of industry and home. The industrial line focuses on high reliability, wide temperature adaptation, and redundant design; the home line focuses on miniaturization, low power consumption, and intelligent interconnection to achieve precise matching of technical solutions.

Supply chain collaborative optimization: with upstream SiC/GaN Chip manufacturers and magnetic material suppliers are deeply bound to jointly develop customized devices to reduce costs while improving product performance; two industrial-grade and home-grade supply chain systems have been established to ensure delivery stability in different scenarios.

Implementation of scenario-based solutions:

Industrial end: Deeply engaged in high-frequency scenarios such as 3C manufacturing, new energy automobile parts, and lithium battery equipment, providing customized power supply solutions, supporting installation, commissioning, and operation and maintenance services.

Home: Cooperate with leading smart home brands to develop standardized modules to adapt to smart home appliances, security equipment, smart lighting and other terminals, and break through protocol compatibility barriers.

Compliance and certification first: Plan in advance for IEC 61800 and UL 508 certification in industrial scenarios, and CCC, CE, and FCC certification in home scenarios to ensure that products can quickly enter the target market.

5. Future trends: from power supply components to energy management nodes

Industrial side: Upgrading to energy interconnection nodes: industrial ACDC converters will integrate more energy management functions, link with photovoltaic and energy storage systems, and realize production lines "Spontaneous self-use and surplus power grid connection" help factories create a green and low-carbon production model.

Home side: Integrated into the whole-house energy management system: Home ACDC converters will become the core node of the home energy network, connecting rooftop photovoltaics, home energy storage, and smart home appliances to achieve intelligent distribution and dispatch of energy and promote "Zero Carbon Family" is launched.

Accelerating technology integration: The cost of SiC and GaN devices continues to decline, and cross-scenario penetration will be achieved; AI The in-depth application of the algorithm will allow the ACDC converter to have autonomous learning capabilities, dynamically optimize the power supply strategy based on the operating status of the equipment, and further improve energy efficiency and reliability.
