Smart Home Appliances Power Supply Solutions

Green environmental protection and intelligent concepts are rapidly reshaping people's lifestyles. The global smart home appliance market size in 2022 was US$38.02 billion, and it is expected to reach US$60.4 billion by 2026, with a compound annual growth rate (CAGR) of 12%.

As a major exporter of home appliances, the green transformation, intelligentization, and high-end upgrading of my country's home appliance industry have become an inevitable trend. The government has successively issued several policies, such as "Promoting Green Smart Home Appliance Consumption in 2023," to encourage the development and innovation of the smart home appliance industry.

Industry Demand

Compared with traditional home appliances, smart home appliances require more rigorous and complete stress testing and inspection in product research and development and production qualification assurance. To ensure that the product meets the standard requirements, the production line needs to be equipped with an AC variable frequency power supply to provide accurate and high-quality simulated power grid for testing.

1. Testing requirements

For smart appliances exported abroad, they must not only adapt to the fluctuations of the power grid within the standard requirements, but also meet the relevant certification standards of different countries (such as EU CE certification, US UL certification, Japan FSE certification).

2. Industry pain points

The test system has a low degree of integration.

Test data cannot be quickly fed back.

Test standards are becoming more stringent, and the output accuracy is low.

There are a few types of interfaces, and it is difficult to connect.

Large space and low efficiency.

Unable to meet the test standards of multiple countries.

Solutions

Ainuo Instruments has been deeply involved in the home appliance testing industry for many years. Aiming at the difficulties in testing smart home appliances, it has specially developed and launched the ANFH series of AC variable frequency power supplies, which can simulate the voltage and frequency of power grids in various countries to the greatest extent. It adopts STM32 digital control, instantaneous waveform control, and high-frequency pulse width modulation (SPWM) and other technologies, and has the advantages of fast response speed, high output accuracy, and excellent waveform quality. The 19-inch standard chassis size design is small in size and rich in interfaces. It can be directly installed in a standard cabinet to meet the requirements of various use occasions, such as testing, system integration, and production lines.

The ANFH series can communicate via RS-485, RS232, GPIB, or LAN. In addition, the power supply can be used with a computer host, and users can test home appliances through a computer host.
