SVPWM优化控制策略仿真研究

Study on simulation of optimal control strategy of SVPWM

本文针对大容量高电压领域提出了减小开关损耗的优化SVP-WM控制方法。该方法根据逆变器的开关损耗与具体的调制方法、负载功率因数角的关系,通过对零矢量在脉宽中的不同分配使开关次数减少,从而减小开关损耗。通过仿真验证了理论的正确性,为以后的硬件研究和软件设计打好了基础,有效地缩短了实际设计时间。

To extremely reduce switching losses in high-voltage and large-capacity fields, an optimal control strategy of SVPWM is discussed in the paper. Based on the relationships between the inverter losses and the control method, as well as the power factor of the load, the method can reduce the switching frequency to get the less switching losses according to the different allocation of zero vectors. The theory is validated by simulation, which not only lay the foundation down for hardware and software design, but also effectively shortens the developing periods.
