In today's era of rapid development in electronic technology, power electronics technology has gained increasing attention. Among them, the upgrading of power supply and voltage regulator technology has further promoted the development of related electronic devices and components. Whether in people's daily life or in modern electronic warfare, the power system, as its power source, is of an obvious and undeniable position and importance. However, the quality of power products in China, whether for military or civilian use, has a significant gap compared to similar products from abroad. Therefore, adopting international advanced standards, learning advanced foreign technologies, and quickly making the quality of our power products catch up with the international advanced level is something that all those engaged in power research should strive for.
