Description

technical field [0001] The invention relates to a high-power centralized microwave rectifier circuit, which belongs to the field of microwave energy transmission. It is used to convert the input microwave energy into direct current. Background technique [0002] With the rapid development of the world economy, energy and environmental problems are becoming increasingly severe. Clean energy has become a new energy strategy advocated by various disciplines, and the main solutions to energy problems centered on solar energy, wind energy, and bioenergy have been formed. Most of the solutions are limited by factors such as environment, climate, and region, and there are defects to a certain extent. At the beginning of the 20th century, microwave power transmission (MPT: Microwave Power Transmission) entered the field of vision of researchers. Microwave power transmission has the advantages of high efficiency, no pollution and no climate restrictions. In 1968, Dr. Peter Glaser ...
