Rotary energy transfer device

Abstract

The invention discloses a rotary energy transmission device, which mainly solves the problems of unstable electrical parameters, difficult integration of three-phase coils and unbalanced self-inductance and leakage inductance of three-phase coils in the prior art. The device includes two sets of coils (1, 2). , two PCB boards (5, 6) and fixing parts (4), the transmitting coil (1) is embedded in the transmitting PCB board (5), the receiving coil (2) is embedded in the receiving PCB board (6), and the two PCBs The fixing members (4) on the board are all provided with magnetic conductors, respectively forming a transmitting end and a receiving end. Each PCB board is a circular multi-layer structure, on which there are mounting holes for the magnetic conductors and fixing holes for the insertion of the fixing parts, and are evenly arranged on the PCB board in three circles: inner, middle and outer. . The two coil-embedded PCB boards are isolated by air, the invention balances the self-inductance and leakage inductance of the three-phase coil, improves the safety and reliability of energy transmission, and can be used in space solar power stations or ground energy transmission occasions.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a rotating energy transfer device, which can be used in space solar power stations or ground energy transfer occasions. Background technique [0002] Solar energy is a renewable green energy, which will play an important role in solving the world's energy shortage and environmental pollution problems. Compared with the ground solar power station, the space solar power station SSPS can work continuously because it is not affected by day and night and weather, has high solar energy utilization efficiency, and has broad application prospects. [0003] A space solar power station refers to a power system that converts solar energy into electrical energy in space and then transmits it to the ground through wireless energy transmission. The space solar power station is mainly composed of three parts: solar power generation device, energy conversion and transmission device, ground r...

AI Technical Summary

Problems solved by technology

Traditional non-contact energy transmission is mostly a single-phase system, but the ability of a single-phase system to transmit energy is obviously not as good as a three-phase system

However, the traditional three-phase system is difficult to integrate into one device, and the rotation will cause instability of electrical parameters and unbalanced three-phase system.
