Description

technical field [0001] The invention relates to an inverter source for wireless power transmission based on six-pulse wave controllable rectification, and belongs to the technical field of wireless power transmission for rail-type electric vehicles. Background technique [0002] At present, there are often charging infrastructure problems on the ground in the development of rail-type electric vehicles. Since the contact charging electrodes are exposed, the natural weathering and corrosion speed is relatively fast, and there may be arcing and carbon deposition problems, which require regular cleaning, maintenance and repairs. The safety of production and life and maintenance personnel will be affected to a certain extent. At the same time, because the principle of contact charging limits the charging speed and aerodynamic shape of rail transit vehicles, it is not convenient to increase the speed of rail transit vehicles. Contents of the invention [0003] In order to solve...
