Description

technical field [0001] The invention relates to an energy supply method, in particular to an integrated method of air-cooling and high-level energy supply for high-voltage power electronic devices. Background technique [0002] High-voltage power electronic devices are the core components that make up high-voltage DC equipment. In practical applications, power electronic devices are connected in series at a high-voltage potential, and the drive circuit is directly electrically connected to it, and is at the same potential, such as figure 1 shown. The driving circuit can only guarantee reliable operation under the condition of obtaining energy. It is at a high potential, which is different from the ground potential, so that it cannot be directly connected to the ground power supply system. It supplies energy. In the DC line, there is no alternating electromagnetic field, and it is difficult to directly obtain energy. Therefore, it is necessary to supply high-level energy to...
