- the present invention relates to an electric transmission device in the field of electric transmission, and particularly to a multifunctional electric energy converter.
- Electric energy is widely used in various occasions. With the development of technology, people have developed a variety of electric power transmission devices, such as transformers that change voltage, in order to rationally use the electric energy of the power grid and meet the different needs of various electrical facilities.
- the common disadvantage of these power transmission devices is that they have a single function and cannot fully achieve the ideal working conditions, such as the contradiction between the transformer's ability to transform and its own consumable costs and high-temperature insulation; the high-voltage transmission of the inverter and its own
