With the rapid development of all aspects of modern society, efficient, energy-saving, sensitive and fast home appliances have obviously become the theme of life. As manufacturers of these home appliance industries, they have higher and higher requirements for some supporting equipment on how to improve the speed of detection and production. As for the skills of variable frequency power supply for smart appliances, the requirements of energy conservation, environmental protection, fast and sensitive use make the high frequency of power converter and the digitization, intellectualization and networking of microprocessor or DSP chip as the core carrier become the development trend of smart appliances.
Specifically, there are the following key aspects:
1. The high frequency trend improves the switching frequency of variable frequency power supply, which can effectively reduce the volume and weight of equipment. In order to further reduce the volume and weight of equipment, remove the heavy power frequency isolation transformer and select high frequency isolation, which widens the working voltage range, eliminates the audio noise of transformer and inductor, and improves the dynamic response ability of output voltage togethe
2. Digital trend now digital signal processing skills are becoming more and more sophisticated, showing more and more advantages: it is convenient for computer intelligent and sensitive processing and control, simplify the complexity of hardware circuits, improve the anti-interference ability of the system, facilitate software package debugging and after-sales service, especially the use of wireless communication connection and networking skills, The use of fully digitally controlled variable frequency power supply solution is extremely excellent in system performance integration and system cost control. It is a revolutionary upgrading road for the intelligent home appliance industry.
3. The significance of green power supply has two levels: the first is significant power saving. Power factor correction skills and soft switching skills are selected at the input of power grid. Improving the input power factor is of great significance. It can not only reduce the pollution to the power grid, reduce the reactive power loss of municipal power, play the role of environmental protection and energy saving, but also reduce the corresponding investment and improve the operation reliability. In the future, the power supply skills will be developed towards high efficiency, high power factor and high reliability, and continue to complete low harmonic pollution, low environmental pollution, low electromagnetic interference, miniaturization and lightweight. So as to provide a strong technical guarantee for the development of green power products and equipment in the future, which will also be the inevitable result of the development of modern power supply. To sum up, it is known that the household appliance variable frequency electric control power supply products contain great market opportunities in the future.
