摘　　要：开关电源的设计与输入/输出电压、功率和电路拓扑结果密切相关。对于所设计的电路性能通常采用实际测试的办法获得,费时费力。因为难以描绘出开关电源的传递函数,很难采用传统的仿真软件如matlab进行方针和分析。Saber因其丰富的元件模型、友好的人机界面,使得其非常适用于开关电源的设计与仿真。以DC/DC开关电源的设计与仿真为例,详细介绍了开关电源的设计过程,给出了saber的仿真设置。结果表明,仿真结果符合实际情况,图形直观,便于对仿真电路进行分析和校正,为开关电源的设计提供了一个强有力的工具。Design of switching power supply is closely related to input/output voltage, power and circuit topology. The performance of designed circuit is usually obtained through actual test, which is time - consuming and laborious. Because it is difficult to depict the transfer function of switching power supply, so it is difficult to design and analyze with traditional simulation software such as MATLAB. Saber is very suitable in design and simulation of switching power supply for its rich element models, friendly man - machine interface. With design and simulation of DC/DC switching power supply as an example, the process of design of switching power supply is not only illustrated, but also the Saber simulation settings. The result shows that, the simulation results is in accord with practical situation, graphical intuitive, easy to analyze and correct simulation circuit, so Saber provides a powerful tool for design of switching power supply.
