Electric energy is one of the most crucial forms of energy in human society. To utilize electric energy effectively, one cannot overlook power electronic technology, which converts the form of electric energy. This involves controlling voltage, current, and frequency. Power electronics is a technology that utilizes power semiconductor devices to convert and regulate electrical energy. It amalgamates three disciplines: electricity, electronics, and control theory. As the core of power electronics technology, “one generation power devices, one generation topology and technology”. Mastering the key technology of power semiconductor devices is essential to propel the advancement of power electronics.
