Description

technical field [0001] The invention relates to the field of current and voltage transformation, in particular to a semiconductor DC photoelectric transformer. Background technique [0002] In daily applications, traditional power transmission mainly uses alternating current for transmission, mainly because alternating current is easy to transform, easy to realize long-distance power transmission, and low-voltage power distribution and transformation with users. However, the use of AC transmission has great defects: first, the inductive reactance effect generated by alternating current cannot be ignored, especially for high-frequency alternating current, its inductive reactance effect will have a great impact on alternating current; at the same time, due to the existence of skin effect, making The effective area of ​​the AC transmission wire is small, and a large amount of electric energy will be lost in the process of long-distance power transmission. Secondly, AC transmis...

[0002] In daily applications, traditional power transmission mainly uses alternating current for transmission, mainly because alternating current is easy to transform, easy to realize long-distance power transmission, and low-voltage power distribution and transformation at the user end.

However, the use of AC transmission has great defects: first, the inductive reactance effect generated by alternating current cannot be ignored, especially for high-frequency alternating current, its inductive reactance effect will have a great impact on alternating current; at the same time, due to the existence of skin effect, making The effective area of ​​the AC transmission wire is small, and a large amount of electric energy will be lost in the process of long-distance power transmission

At present, this kind of converter equipment is difficult to manufacture and expensive. Therefore, the application scope of DC power transmission at this stage is mainly limited to long-distance large-capacity power transmission and submarine cable power transmission, which greatly limits the application field of DC power transmission.
