Abstract：Focusing on the central position of AC power frequency converter in the development of the national

economy，emphasizingd their critical impact on the safety and efficiency of industrial production. In view of the rapid development of power electronics technology，the field of AC power frequency converter has made remarkable progress，but also faces many challenges，such as uneven product quality，and there is an urgent need to optimize the industry order to improve the overall quality level. By comparing and analyzing the development status quo of power supply systems at home and abroad，the high standard of product reliability required by the international community was revealed，and provided an in-depth analysis of the problems that exist in China's AC power frequency converter products in terms of reliability，standardization and regulation. In order to promote the high-quality development of the industry，a series of strategies were put forward：strengthening product reliability technology research and development，building a standardized evaluation system，ensuring the effective implementation of standards，promoting the power supply product certification system，and strengthening the operation and maintenance regulatory mechanism. These comprehensive measures are aimed at optimizing the industry ecosystem，improving product quality and safety，and thus promoting the high-quality，sustainable development of the AC power frequency converter industry.
