摘要

介绍了一种不受输入输出电压设置和负载电流变化影响而具有统一频率特性的开关电源变换器电路的设计方法。每个电路块表示为一个等效的小信号传递函数。在连续导通模式(CCM)和不连续导通模式(DCM)下，对全反馈回路进行了稳定性分析。此外，还介绍了一种开关电源变换器的系统和电路仿真方法，该方法能够快速、精确地模拟开关电源的瞬态响应和频率特性。它的特点包括模拟时间的加速，以及同时使用类似spice的模拟模拟器和行为模拟器的能力。我们的结论是，复杂的电路设计和开关电源变换器的仿真现在是可用的。

Sophisticated circuit design and simulation method for switching power converters

We introduce a method for designing switching power converter circuits with unified frequency characteristics independent of the input and output voltage settings and the load current change. Each circuit block is expressed as an equivalent small signal transfer function. Stability analysis of the total feedback loop was performed in both the continuous conduction mode (CCM) and discontinuous conduction mode (DCM). In addition, a system and circuit simulation method for switching power converters that enables fast and precise simulation of a transient response and frequency characteristics is introduced. Its features include acceleration of simulation time, and the ability to use a SPICE-like analog simulator and a behavioral simulator at the same time. We conclude that sophisticated circuit design and simulation of switching power converters are now available.
