应用于磁耦合谐振式无线电能传输系统的高效率E类逆变电源设计方法
Design Method of High Efficiency Class-E Inverter Applied to Magnetic Coupled Resonant Wireless Power Transmission System
摘要
Abstract
As one of the most efficient power amplifiers, the ZVS class-E inverter has been widely used as a driving power source for magnetic coupled resonant wireless power transmission (MCR-WPT) systems.Its efficiency is not only the efficiency of wireless power transmission through coils, but also the efficiency of inverter.The relationship between output power, design parameters and load of ZVS class-E inverter has been obtained under the rated optimal operation mode.Equivalent model of four coil structure MCR-WPT system driven by class-E inverter was established with the theory of circuit mutual inductance, and the load matching was optimized with the rated optimal operation mode of class-E inverter.After that, the design method of high efficiency MCR-WPT system for power supply adapting to load was given.It is proved by experiments that this design method can achieve high matching of the inverter power at the transmitting end and the load at the receiving end, and the output power can be greatly improved.关键词
