| 摘 要： | 为了减化逆变电源的各种逆变控制算法、提高逆变效率,提出了一种基于DSP的实现的、可变频的异步调制算法首先对算法进行了理论推导,进而提出了该算法的程序实现方法.实验证明,该算法不仅具有程序实现简单、逆变输出稳定、控制精度高等众多优点,同时还具备优良的变频调制特性.通过加入其它控制算法,该算法就可以很方便地应用于诸如变频调速控制、UPS逆变控制、逆变锁相控制等各种实际应用中.图5,表2,参10.

| Abstract: | To simplify the inverter's control and increase it's efficiency,a DSP based (frequency-variable)asynchronous modulation algorithm was present. With the theoretic analysis,the program for this algorithm was offered. The experiment proved that this algorithm have many advantages,such as easy realization, stabile inverter output,high control precision,etc. Through adding some special inverter control technique, the algorithm can easily apply to many specific applications like VVVF control,UPS control and so on. 5figs.,2tabs.,10refs. |
