| 摘 要： | 本文首先分析了数字式逆变电源的原理,采用了基于输出电压反馈的双闭环控制结构,并结合TI公司生产的高速、低功耗、高性能的16位数字信号处理器TMS320LF2407A设计了一台3kVA样机,进行了完整的系统软硬件设计,最后得出了系统的实验结果;结果表明,系统具有较好的动静态性能:空载时,输出电压的THD为0.82%;带阻性负载时,THD为1.68%。

| Abstract: | The principle of digital inverter is analyzed first and the double closed loop control structure of output voltage is adopted. The sample with 3KVA is designed combining the digital signal processor with high performance and low power consumption produced by TI Company. The design of hardware and software of system is presented here and the results of system are obtained. The dynamic and steady performances of system prove to be better: the THD of output voltage is 0.82% without load; the THD is 1.68% with Resistive load. |
