Several thoughts on the development of my country's power supply industry [Copy link]

In view of the review and analysis of the development plan of my country's power supply industry, we can get many useful inspirations, especially the future development trend of my country's power supply industry, which can be seriously considered:

　　(1) By 2001, the switching power supply market in the United States was still growing at an average annual growth rate of more than 10%. However, my country is still a developing country and its switching power supply market is far from being developed. Phase-controlled power supplies still account for a considerable proportion of my country's power supply industry. We believe that from a long-term and strategic point of view, power supplies using PWM technology will eventually replace various types of phase-controlled power supplies. Therefore, we must pay enough attention to focusing on the independent development and production of domestic switching power supplies and fully developing and occupying the domestic switching power supply market, so as to avoid repeating the domestic small and medium-power general-purpose inverter market, which was almost entirely occupied by foreign products.

　　(2) From the analysis of various types of switching power supplies produced in the United States, it can be seen that low-power (below 1-2kW) switching power supplies account for a considerable proportion of the total output value of the U.S. power supply industry. Therefore, we should make every effort to strengthen the research, development and large-scale production of low-power switching power supplies to quickly form our own switching power supply industry.

　　(3) Low-power switching power supply is a kind of power electronic product with high technical content. High reliability is the first important indicator, followed by EMI, PFC, efficiency, volume, weight and cost, which are also important factors for whether our products can participate in the international market competition. Therefore, it is very important and urgent to improve the technology and production team of my country's power supply industry.

　　(4) In the process of developing and growing the power supply industry, high-frequency magnetic materials, components and module manufacturing technologies must be developed simultaneously. Their research, development and production are closely related to the formation of my country's switching power supply industry and cannot be taken lightly.
