摘要
DSP数字化控制逆变器,简化了控制电路,使控制功能灵活性得到改善.选用TI公司的TMS320LF2407A数字信号处理器作为电力逆变器的控制核心,取代以往传统的模拟控制方式,实现了闭环控制算法.完成了硬件系统和软件算法的完整设计,设计出一台50 Hz、1 kVA的样机,并进行实验验证,逆变器空载和满载时输出电压总谐波含量THD<5%,结果表明该系统性能良好.
The digital control of inverter not only simplifies the control circuit, but also improves the flexibility of control function. DSP TMS320LF2407A produced by TI Corporation was selected as the controller to carry out the closed-loop arithmetic. The hardware and software of the system are given, a 1KVA inverter sample was designed, at the same time, the experiment was carried out. The experiment shows the system achieves good dynamic and static performance.
