中文摘要: 为了解决对三相无线电能传输系统传输功率的有效控制问题,基于电压型三相串联谐振逆变器,在传统180°导通模式的基础上,提出了一种新型的开关管开通-关断混合对称控制模式:通过在开关管180°开通过程中加入关断短脉冲,在开关管180°关断过程中加入开通短脉冲,改变系统谐振补偿网络等效输出线电压和相电压,实现系统功率传输能力的有效控制。通过对该系统工作模式的分析,推导出系统功率传输能力与开关短脉冲对应电角度之间的函数关系,为无线电能传输系统的设计和分析提供了理论依据。仿真和实验结果证明了该新型控制策略可以有效地控制传输功率,同时验证了理论分析的正确性。
Abstract:In oder to effectively control the output power in three-phase wireless power transfer system, taking the voltage-fed three-phase series resonance inverter as an example, based on traditional 180° control mode, a new control mode named switch on-off mixed symmetric control mode was proposed by adding a short cutoff pulse in the 180° conduction process of the switch, and adding a short setup pulse in the 180° block process symmetrically. The equivalent output line voltage and phase voltage of the resonance compensating network would be varied, which can effectively control the output power of the inverter system. By mathematical modeling, the functional relationship between the power transmission capacity and the pulse electrical angle was derived, which provids a theoretical basis for system design and analysis. From the simulation and the experimental results, it could be concluded that the output power of system could be controlled by this new control scheme, meanwhile, the theoretical analysis was verified.
