感应电能传输系统基于阶梯波合成技术的谐波消除和脉冲密度功率调节方法
Harmonic Elimination and Power Regulation with Pulse Density Modulation Based on Staircase Waveform for Multilevel Inverters in Inductive Power Transfer System
摘要
Abstract
In order to improve the output power of the system,a cascaded inverter based on transformer for inductive power transfer was presented in this paper.Firstly,the harmonic elimination equation was established by using the staircase waveform synthesis technique.Then,the problem that the output power regulation range is small or the total harmonic distortion (THD) value is large when regulating the pulse width or the phase shift under the condition that only the 3rd harmonic eliminated was analyzed.In order to improve the efficiency of the system,3rd and 5th harmonics were eliminated simultaneously,and the optimal pulse width and phase shift angle based on THD was selected.In order to regulate the output power under condition of eliminating 3rd and 5th harmonic,a novel pulse density modulatiorn (PMD) regulation approach based on staircase waveform was proposed in this paper.The feasibility and effectiveness of the proposed method was verified in simulation experimentation with 30kW inductive power transfer (IPT) system.The experimental results show that based on the staircase waveform pulse density control,the output power can be regulated with eliminating 3rd and 5th harmonic in whole load.The additional loss of harmonic and switch loss in light load are reduced,and efficiency of the system is improved.关键词
