摘　　要：讨论了 SPICE程序对于电流控制开关电路模拟的问题。模拟 DC- DC转换器、大功率开关和大功率电路系统的关键在于找出 SPICE程序能接受的代替开关元件 ,文章给出了建立理想开关 SPICE宏模型的方法和多种电压控制开关、电流控制开关的子电路模型。该方法简便易懂 ,在电路系统的设计仿真中有良好的应用价值。Simulation problems of current mode control switch in SPICE are discussed. Switches description by applying acceptable elements in SPICE is important for the simulation of DC DC converters, switching mode power supplies, and power electronic circuits. Several methods for the construction of ideal switch in SPICE macro model and sub circuits models of voltage control switch and current control switch are presented. These methods are simple, effective, and practical.
