The power supply manufacturing industry must keep up with the times, seize the opportunity for development, and choose the right direction. So, what are the trends in 2021 for variable frequency power supplies? According to the editor of the 400HZ variable frequency power supply, the key directions are mainly high-frequency, digitalization, and greening.
1. The trend towards high-frequency transactions
Increasing the switching frequency of the inverter power supply can effectively reduce the size and weight of the device. To further decrease the size and weight, a bulky power frequency isolation transformer has been removed, replaced with high-frequency isolation. This expands the working voltage range and eliminates audio noise from transformers and inductors, while also enhancing the dynamic response capability of the output voltage.
2. Digitalization Trend
As digital signal processing technology becomes increasingly refined and mature, its adoption facilitates intelligent and flexible computer control, simplifies the complexity of hardware circuits, enhances system anti-interference capabilities, and aids in software package debugging and after-sales service. Particularly in the application of wireless communication connections and networked technologies, the full digital control variable frequency power supply solution excels in system performance integration and cost control, marking a revolutionary upgrade path for the intelligent home appliance industry.
3. The trend towards greenification
The meaning of Green Power has two layers: Firstly, it significantly reduces energy consumption, achieved through the use of power factor correction technology and soft switching technology at the grid input end. Improving the input power factor is of great significance, as it not only reduces pollution to the grid and minimizes reactive power losses in the municipal electricity supply, contributing to environmental protection and energy conservation, but also reduces corresponding investment and enhances operational reliability. In the future, power supply technology will evolve towards high efficiency, high power factor, and high reliability, continuously achieving low harmonic pollution, low environmental pollution, low electromagnetic interference, and miniaturization and lightweighting. This will provide a strong technical guarantee for the development of green power supply products and equipment in the future, which will also be an inevitable outcome of modern power supply development. In summary, the market opportunities for home appliance inverter control power supply products are substantial in the future.
