摘要
本文讨论了一种基于EPROM存储的全数字式高频PWM调制器。该调制器占用微机时间极少,控制精度较高,电路结构简单,实现方便,适用于全桥DC-DC变换器各种控制方式。本文对该调制器的基本工作原理进行了详细分析。并按上述原理实际制作了一台实验样机。样机波形证明了上述全数字控制器原理的正确性及实用中的可行性。
A novel EPROM-based digital PWM controller is discussed in this paper. Which has the following advantages such as occupying only a Httle time of microcomputer, having higher control precision and simpler circuit, fitting to various control strategies for full bridge DC-DC converters. The fundamemtal principle of this controller is analyzed in this paper in detail. A prototype based on the above principle is implemented. wave-formes demonstrate the feasibility of the new digital PWM controller.
