摘要
为了使感应耦合电能传输系统可以在不同电压等级的输入电源下均能满足负载的供电需求,提出了一种宽电压增益逆变器。该逆变器可以宽范围调整输出电压增益(包括升压和降压两种输出模式)以实现系统输出功率的宽范围调节,且只含有2个可控功率开关器件。首先介绍宽电压增益逆变器的拓扑结构,并结合工作波形和等效电路模型分析其工作原理;随后对其工作性能进行分析,包括逆变输出电压增益、系统输出功率以及功率开关器件应力;最后,建立实验装置进行实验分析和验证。实验结果证明了理论分析的正确性和本文所提逆变器的可行性。
In order to make output power of the inductively coupled power transfer(ICPT) system meet power supply demand of load under different input voltage levels, this paper proposes a kind of wide voltage gain inverter which can regulate output voltage gains in wide range under boost and buck modes to realize wide range regulation of system output power with only two controllable power switches. It firstly introduces topology of this inverter and analyzes the working principle combining working waveforms and the equivalent circuit model. Then it analyzes working performance of the inverter including inverter output voltage gain, system output power and stress of power switches. Finally, it establishes experimental prototype for analysis and verification. The experimental results prove correctness of theoretical analysis and feasibility of the proposed inverter.
