摘要
针对目前多电平变频器在国内、外所面临的脉宽调制(PWM)控制专用IC的空白现状,研究开发了一种基于CPLD的单元组合式多电平变频器拓扑的移相PWM控制专用电路模块。该电路模块利用了全数字化数据存储方式,具有方案新颖、控制可靠等优点,为开发移相PWM控制专用IC奠定了基础。
A new kind of PWM control circuit module of the cell cascaded multilevel inverter which is based on the CPLD is explored, in allusion to the blank actuality of special purpose PWM control IC which the multilevel in- verter is faced with at the present time. This circuit module has utilized the total digital data storage mode and has the advantage of scheme novelty and reliability of control etc, which has settled the basis for exploring the special purpose PWM control IC.
