直流电源级联式多电平逆变器控制策略的实现

摘要

针对一种新型的直流电容分压式电源级联型多电平逆变器的结构分析其spwm控制策略。详细描述了利用数字信号处理器（DSP）TMS320F2812d和可编程逻辑器件（FPGA）EP2C8Q208C8相结合实现这种控制策略。此控制结构利用数字信号处理与可编程逻辑器件控制的灵活性可以对逆变器输出电压、输出频率、相位进行精确调节。满足不同的应用对象。%On a new type of dc power supply pressure let points cascade type the multilevel inverter structure analysis of its SPWM control strategy. Detailed descriptions of the use of digital signal processor （DSP） TMS320F2812d and programmable logic devices （FPGA） EP2C8Q208C8 combined control strategy to achieve this, the control structure using digital signal processing and programmable logic device control flexibility of inverter output voltage, frequency and phase output accurate adjustment, meet different application object.
