摘要
提出了一种基于CPLD(复杂可编程逻辑器件)的单相逆变控制器的设计方案.该控制器包含PI模块、HPWM模块、正弦波产生模块及三角波产生模块等环节,可实现单相逆变器闭环控制及混合脉宽调制策略,并取得高质量的输出质量和变换效率.系统仿真和实验结果验证了分析的正确性.
A CPLD-based single-phase inverter controller design was proposed. The entire controller contains PI module, HPWM module, sine wave and triangular wave generated modules. The block diagram of hardware design and CPLD internal structure were shown. Close-loop control and HPWM came true by this controller, and the output of inverter has good performance and high efficiency. Simulation and experimental results verified these analyses.
