摘要

提出了一种电流编程模式(CPM) DC/DC变换器稳态设计的新方法。该方法根据线路电压、负载电流、控制电流和稳定人工斜坡之间的关系推导出一组方程。通过快速大信号仿真和实验测量验证了归一化方程的正确性。这些方程绘制在变换器直流输出平面上(输出电流与输出电压的关系图)，其中表示了与不同人工坡道和不同工作模式边界相关的特性曲线。提出了一种输入电压和输出电阻性负载均变化的CPM变换器的一般设计方法。通过这种方法，设计时间可以大大减少，并且可以进行系统的设计权衡，以确保在所需的线路和负载变化范围内正确运行转换器。

Steady-state and large-signal design of current-programmed DC-to-DC converters

A new method for steady state design of current-programmed-mode (CPM) DC/DC converters is presented. The method uses a set of equations derived based on the relationships between line voltage, load current, control current and the stabilizing artificial ramp. The set of normalized equations are verified by a fast large-signal simulation and experimental measurement. These equations are plotted on the converter DC output plane (a graph of output current versus output voltage) in which characteristic curves related to different artificial ramps and boundaries of different operating modes are indicated. A general design procedure is presented for a CPM converter with both input voltage and output resistive load varied. By this means, the design time can be significantly reduced and systematic design trade-offs can be made to ensure correct converter operation over the desired range of line and load variation.<>
