摘要
为了给滤波器和谐波抑制算法设计提供理论基础,首先介绍了有源中点钳位五电平逆变器的工作原理和载波移相调制算法;然后,利用双重傅里叶变换原理和Bessel函数对ANPC-5L逆变器的相电压谐波进行了理论分析,总结了谐波分布和THD变化规律。解析结果与仿真实验结果证明了所提分析方法的正确性。
In order to provide theoretical basis for the design of filter and harmonic suppression algorithm,the operation principle and the phase-shift pulse width modulation algorithm of ANPC-5L inverter were introduced firstly.And then,the phase voltage harmonics of ANPC-5L inverter were analyzed by using the double Fourier transform and bessel function,with greatly reduced calculation and simple yet clear process.This paper summaries the law of harmonic distribution and THD variation were summarized.The analytic result agrees well with the simulation and experimental result,which verifies the correctness of the proposed analysis method.
