J.；Prieto, J 【期刊】 IEEE Transactions on Power Electronics 【卷期】2013/28 【abstract】This study presents a space vector pulsewidth modulation algorithm for five-phase converters operating in the overmodulation region that forbids the use of zero vectors, covering the whole overmodulation range and providing minimum $xhbox-y$ voltages. Avoiding zero vectors reduces the content of low-order current harmonics and, at the same time, reduces the common-mode voltage (CMV) by 40%. The method is first implemented using medium and large voltage space vectors, showing good performance in terms of current harmonic content. Then, the algorithm is applied to the case when four large vectors are used, further reducing the peak-to-peak CMV by 80% and still demonstrating a satisfactory performance. Both methods are experimentally compared to existing overmodulation algorithms obtaining better current quality and lower peak-to-peak CMV. A General Space Vector PWM Algorithm for Multilevel Inverters, Including Operation in Overmodulation Range 【作者】 Amit Kumar Gupta 【期刊】 IEEE Transactions on Power Electronics 【卷期】 2007/2【abstract】This paper proposes a simple space vector pulsewidth modulation algorithm for a multilevel inverter for operation in the overmodulation range. The proposed scheme easily determines the location of the reference vector and calculates on-times. It uses a simple mapping to generate gating signals for the inverter. A five-level cascaded inverter is used to explain the scheme. The scheme can be easily extended to a n-level inverter. It is applicable to neutral point clamped topology as well. Experimental results are provided for five-level and seven-level cascaded inverters. Space Vector PWM Method for Five-Phase Two-Level VSI With Minimum Harmonic Injection in the Overmodulation Region【作者】Gonzalo Carrasco；Cesar A. Silva 【期刊】IEEE Transactions on Industrial Electronics 【卷期】 2013/6 【abstract】In this paper, a novel solution to the space vector modulation (SVM) of a five-phase voltage-source inverter (VSI) in the overmodulation region is presented. The method is based on an explicit minimization of the harmonic injected to overmodulate a voltage, which is achieved by using all the degrees of freedom provided by the SVM in a five-phase VSI. The performance and feasibility of the method are evaluated through simulations and experiments. Furthermore, the experimental results are compared with those of other methods of overmodulation found in the literature, showing the superior performance of the proposed method in terms of the amplitude of the harmonic injection required to achieve maximum dc-link voltage utilization. Control method for IPMSM based on perfect tracking control and PWM hold model in overmodulation range 【作者】 Miyajima, Takayuk【期刊】International Power Electronics Conference 【卷期】 2010/3【abstract】Interior permanent magnet synchronous motors (IPMSMs) are employed for drive motors of electric and hybrid vehicles. Therefore, the control method in overmodulation range of inverter is important for fast torque response and expanding operation range of IPMSM. In this paper, the control methods based on perfect tracking control and PWM hold model are proposed in overmodulation range. The proposed methods do not need to switch controllers in overmodulation range. One of the proposed methods simultaneously prevents windup phemonemon and voltage saturation which is caused by harmonic current with PWM hold model. Finally, simulations and experiments are performed to show the advantages of the proposed methods. A Novel Dynamic Overmodulation Strategy of Direct Torque Control【作者】 Auzani Jidin; Tole Sutikno 【期刊】TELKOMNIKA 2010/08【abstract】This paper describes the dynamic overmodulation strategies for fast torque control of the high-saliency-ratio ac motor. For the high-saliency-ratio ac motor, the dynamic control of both d- and q-axes currents is required for fast torque control with optimal efficiency. However, in transient operation, the d-and g-axes current regulators are easily saturated even at low speed because the stator inductance is designed large enough to generate the desired reluctance torque. With the conventional overmodulation strategies, the current regulation performance degrades severely compared to a nonsalient motor. In this paper, the drawbacks of the conventional overmodulation strategies are investigated and a dynamic overmodulation strategy is proposed to improve the current response to fast transients. For the effective implementation of the strategy, a practical algorithm is also presented. The performance of the proposed strategy is confirmed by computer simulation and experiment with a 3.75-kW axially laminated synchronous reluctance motor and an interior permanent-magnet synchronous motor for 42-V integrated starter-generator applications. 3、 专利文献（中外文各找2篇）：（工科必备）.基于优化的准正弦平顶调制波PWM过调制方法 【发明者】 王榕生 【专利号】 ：CN201310438061.1【摘要】本发明涉及一种基于优化的准正弦平顶调制波PWM过调制方法,其特征在于：首先构建一准正弦平顶波作为调制波,并对三角载波进行调制,然后采用三相PWM过调制算法进行过调制。本发明采用三角载波采样生成三相PWM,在线性区内的最大输出线电压基波幅值较SPWM高19%,显著提升了直流电压利用率。. 一种三电平双模式空间矢量过调制方法及其系统 【发明者】 冯江华;甘韦韦 【专利号】 CN201210115050.5【摘要】本发明公开了一种三电平双模式空间矢量过调制方法及其系统,三电平双模式空间矢量过调制方法包括：计算参考电压矢量的调制比和基本矢量的作用时间；根据调制比确定参考电压矢量所处的过调制区,从而选择不同的过调制模式；若参考电压矢量处于过调制模式一,则根据调制比计算过调制模式一的补偿系数,并根据短矢量的作用时间和补偿系数修正基本矢量作用时间；若参考电压矢量处于过调制模式二,则根据调制比计算过调制模式二的补偿系数,并根据补偿系数修正基本矢量作用时间。本发明原理直观、易于理解、步骤简单、计算量小,便于工程化应用；输出电压幅值相位误差小,谐波含量低,能够有效减少过调制区的中点电位波动。.
