Abstract

The high-frequency voltage generation is the prime requirement for inductive power transfer(IPT) systems. Conventionally for the IPT systems, two-stage conversion (AC-DC-AC) is required for the high voltage frequency generation which increases the complexity and efficiency of the system. This paper presents a new dual capacitor clamped AC-AC converter with Series-Series (SS) configuration for the inductive power transfer applications like charging of Electric Vehicles etc. The proposed converter is bi-directional which will be compatible with both V2G and G2V applications. Moreover, an active power de-coupler is also introduced in the proposed converter for smooth charging of the batteries and filter out the power ripple issue of the conventional AC-AC converter. Design aspects and mathematical analysis are explained in the detail also the feasibility of the proposed converter is verified by the simulation and experimental results on MATLAB/Simulink platform as well as on laboratory prototype.
基于双箝位AC-AC变换器的感应充电系统
高频电压产生是感应功率传输(IPT)系统的主要要求。传统的IPT系统需要两级转换(交直流交)来产生高压频率,这增加了系统的复杂性和效率。本文提出了一种新型的串联-串联(SS)结构的双电容钳位交流-交流变换器,适用于电动汽车充电等感应功率传输应用。所提出的转换器是双向的,将兼容V2G和G2V应用。此外,该变换器还引入了有源功率解耦器,以实现电池的平稳充电,并滤除传统交流变换器的功率纹波问题。文中详细阐述了该转换器的设计方法和数学分析,并通过MATLAB/Simulink平台上的仿真和实验结果以及实验室样机验证了该转换器的可行性。
