摘　　要：开关电源以其诸多优点得到了广泛的应用。LTspice Ⅳ是LT公司推出的功能强大的开关电源设计及仿真软件。文章通过实例来介绍基于LTspice Ⅳ的开关电源设计方法及仿真技术,给出了Boost变换电源的重要观测点波形,并对波形含义进行了解释。The switching mode power supply has been widely used because of its many advantages. LTspice IV is the LT＇s powerful design and simulation software for switching mode power supply. The paper describes the design method and simulation technology of switching mode power supply based on LTspice Ⅳ by using an circurt example, gives the simula-ion waveforms on important test point in the boost convert circurt, and explains the meaning of waveforms.

关 键 词：开关电源 LTspice Ⅳ Boost变换
