摘要
本文提出了一种基于现场可编程门阵列(FPGA)的多电平空间矢量脉宽调制(SVPWM)的有效实现方案。所提方法的目的,是在不带来任何缺点的前提下减少必要的处理需求,并能够自动实现最小开关切换和直流侧电容电压最优控制的多电平开关序列。文中给出了用FPGA控制的两个30kW的三电平IGBT逆变器构成的五电平逆变器实验结果。由于简洁高效的硬件描述语言(VHDL),状态机编程使得整个实现过程非常迅速,在极高的开关频率下也可以采用成本低廉的单芯片来满足要求。
An effective implementation of multilevel space vector PWM (SVPWM) based on Field Programmable Gate Array (FPGA) is presented in the paper. It aims to reduce necessary processing requirements without leading to any disadvantage, and automatically realize minimum switching and multilevel switching sequence of optimal control of capacitor voltage of DC side. This paper shows the research result of a five-level inverter composed of two 30kW three-level IGBT inverters controlled by FPGA. Due to simple and efficient VHSIC Hardware Description Language (VHDL), state machine programming makes the whole implementation process really fast, meeting the demand with cheap single chip under a high switching frequency.
