Problems solved by technology

[0004] The problem is that the traditional inverter uses a single single-phase full-bridge inverter. Due to the limitation of the capacity of the switching device, the output power cannot meet the requirements of high-power electric energy transmission, so that the wireless energy transmission using a single inverter The promotion of technology is very limited
In addition, once a single inverter is damaged, the system will stop working, and the system reliability is poor

Abstract

The invention discloses a multi-transmission and multi-receiving large-power induction electric energy transmission system. The multi-transmission and multi-receiving large-power induction electric energy transmission system comprises more than two induction electric energy transmission units, wherein each induction electric energy transmission unit comprises a sending end and a receiving end, thesending end comprises an inverter and a sending coil, the receiving end comprises a receiving coil and a rectifier, DC input ends of the inverters of all induction electric energy transmission unitsare connected in parallel to a DC power supply, and DC output ends of the rectifiers are connected in parallel to a load. The multi-transmission and multi-receiving large-power induction electric energy transmission system has the beneficial effects that a multi-emission and multi-pickup scheme is employed, the transmission power of the system is greatly increased and can reach hundreds of kilowatts; by designing a plurality of pickup mechanisms, normal working of the other pickup structures are not affected when a certain pickup mechanism is failure and cannot work, and the system is high inintegral reliability and high in redundancy; and since different emission mechanisms have same structures and parameters, different pickup mechanisms also have same structures and parameters, modularmass production is facilitated, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of high-power inductive power transmission systems, in particular to a high-power inductive power transmission system with multiple transmissions and multiple receptions. Background technique [0002] Inductive power transfer technology has been applied to the power supply of high-power equipment such as rail transit trains and electric vehicles. Compared with the traditional power transmission technology with direct physical contact through wires, the inductive power transmission technology does not have problems such as contact sparks, leakage, and influence by rain, snow and dust during the working process. It has the advantages of low maintenance cost, safety and reliability, and high practicability. [0003] The structure and working process of the inductive power transmission system are as follows: the power frequency alternating current is rectified into direct current, the direct current is reversed ...
