Abstract

The invention discloses a 2.4 G microwave wireless single-phase alternating-current-alternating-current conversion circuit, which comprises a receiving antenna unit, a radio frequency switch unit, a positive voltage rectification unit, a negative voltage rectification unit and an alternating-current synthesis unit, wherein the output port of the receiving antenna unit is connected with the common input port of the radio frequency switch unit, the first microwave output end and the second microwave output end of the radio frequency switch unit are respectively connected with the microwave input end of the positive voltage rectification unit and the microwave input end of the negative voltage rectification unit in a one-to-one correspondence manner, and the direct-current output end of the positive voltage rectification unit and the direct-current output end of the negative voltage rectification unit are respectively connected with the positive voltage input port and the negative voltage input port of the alternating-current synthesis unit in a one-to-one correspondence manner. According to the invention, the requirements for collecting microwave energy and converting the microwave energy into alternating current electric energy can be met, the circuit structure of a conventional scheme is simplified under the condition that the overall circuit efficiency is not reduced, and the circuit stability and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of microwave wireless power transmission, and in particular relates to a 2.4G microwave wireless single-phase AC-AC conversion circuit. Background technique [0002] Nowadays, in addition to DC power equipment, there are also AC power equipment. In addition, today's long-distance high-voltage power transmission is mainly based on AC power transmission, so the electrical appliances in life are also mainly powered by AC. In addition, most of the current power transmission methods cannot be separated from cables. The use of cables to transmit electric energy is indeed stable, but in extreme environments, the cost of building high-voltage lines is extremely high, and there are many uncontrollable factors. Therefore, wireless power transmission came into being. Microwave power transmission is generally divided into resonance type and microwave type. The former has a short transmission distance, while the latte...
