摘要
由于在传统的三电平中点箝位式(NPC)逆变器SVPWM调制技术中,各个开关器件以固定的方式进行导通和关断,即开关频率是固定的,因此在开关频率的整数倍处的谐波幅值非常高并且集中在频率整数倍附近处,产生电磁噪声的问题,同时这些开关器件高速运作时的dv/dt、di/dt也非常高,会引起电磁干扰(EMI).针对这些问题,本文在传统随机SVPWM调制的基础上,引入两状态和三状态的马尔可夫链,提出一种基于马尔可夫链的混合随机SVPWM调制方法.运用MTALAB/SIMULINK软件建立了系统仿真模型.仿真结果表明:加入了马尔可夫链的随机SVPWM调制技术,降低了谐波幅值,使谐波在开关频率以及其整数倍次数处变得平顺,得到连续的输出电压功率谱,最终达到了抑制电磁噪声的目的,同时使调制频率在期望中心频率周围更加均匀的分布,改善了电磁兼容性,验证了该方法的有效性和优越性.
Due to in the traditional SVPWM of the neutral-point-clamped(NPC) inverter, each switch device is carried on and off in a fixed way, it means the switching frequency is fixed. Therefore, the harmonic amplitude at the switching frequency is very high and is concentrated at the integer times of the frequency. This may generate electromagnetic noise. At the same time dv/dt and di/dt are very high when these switching devices in high speed operation, it may create electromagnetic interference(EMI). To solve these problems, this paper introduces a Markov chain with two and three states, and proposes a hybrid random SVPWM based traditional random SVPWM. The system simulation model is established by using MTALAB/SIMULINK software. The simulation results show that: The random SVPWM which adds the Markov chain can reduce the harmonic amplitude. The harmonic wave becomes smooth at the switching frequency and the frequency of integer multiple times. It can get the continuous output voltage power spectrum. Finally achieve the purpose of suppressing electromagnetic noise. At the same time, the modulation frequency is more uniform distribution around the desired center frequency. So it can improve the electromagnetic compatibility. The simulation and experimental results show the effectiveness and superiority of the proposed method.
