资料介绍

传统的无线电能传输系统副边采用不控整流电路,仅可进行原边移相角控制。鉴于此,提出了一种副边为斩波电路的无线电能和信息传输系统。具体地,在负载和副边不控桥间增加可控器件和二极管,实现双侧相位角控制;副边通过反馈控制,实现恒定输出的负载电压;基于副边不控桥接收侧结构,通过改变接收侧全控器件开关频率设计信息调制。

The conventional radio power transmission system uses uncontrolled rectifier circuit on the secondary side,which can only control the phase shift angle of the original side.In view of this,a radio power and information transmission system with chopper circuit as its secondary edge is proposed.Specifically,controllable devices and diodes are added between the load and the side uncontrolled bridge to realize phase angle control on both sides.The secondary side achieves constant output load voltage through feedback control.Based on the structure of the receiving side of the sub-side uncontrolled bridge,the information modulation is designed by changing the switching frequency of the full-control device on the receiving side.
