摘要

本文研究了增量调制器的动力学特性及其改进方法。动力学可以简化成一维返回图，一个简单的微分方程。利用回归图，从理论上阐明了非同步运行和脉冲下降现象的机理。提出了一种利用周期性强制开关来稳定同步现象的方法。使用简单的测试电路，在实验室中验证了典型操作。

Analysis of conventional/improved delta modulators as switched dynamical systems

This paper studies dynamics of the delta modulators (DM) and its improvement. The dynamics can be simplified into a 1-D return map, a simple differential equation. Using the return map, we clarify the mechanism for the non-synchronous operation and pulse-dropping phenomenon theoretically. We present a stabilization method of the synchronous phenomena using periodic compulsory switchings. Using a simple test circuit, typical operations are verified in the laboratory.
