中文摘要：
在归纳和总结开关变换器控制技术的基础上,根据电压、电流、电荷和磁通4个基本物理量,将控制技术划分为4类基本型控制（即电压型、电流型、电荷型和磁通型）和组合型控制。按照占空比实现方式的分类,存在两种基本的调制,即脉冲宽度调制和脉冲频率调制。指出开关变换器的控制技术是由＂控制＂与＂调制＂相结合而形成的。利用调制与控制结合的概念,系统地分析基本型控制和组合型控制的工作原理、本质特点、内在关系和优缺点,为开关变换器调制与控制技术的应用提供参考。根据对偶原理,将现有的控制技术拓展到输出恒流控制,并对其进行简要分析。
英文摘要：
On the basis of summarizing the existing control techniques of switching converter, the control techniques are classified into four basic-type controls, i.e. voltage-, current-, charge-, and flux-mode control, and combination-type control, according to the four fundamental physical quantities existed in the circuit. In accordance with the implementation of duty ratio, there are two basic modulations which are pulse width modulation（PWM） and pulse frequency modulation（PFM）. It is proposed that control techniques of switching converters are composed of combining ＂control＂ and ＂modulation＂. Operation principles, intrinsic characteristics, inherent relations, advantages and disadvantages of basic-type control and combination-type control are systematically investigated by the concept of combining modulation and control. They can provide the application reference for the modulation and control techniques of switching converters. According to duality principle, a series control techniques for constant output current which are analyzed in brief are derived from the existing control techniques.
