以固定式集成稳压器为核心,提出了一种可调稳压电源的设计。使用Multisim对电源设计过程进行仿真分析,通过仿真软件中的虚拟仪器、仪表观察和测试电路的特征参数、分析设计电路的性能,完成对电路元件参数调节。实验数据表明,设计的可调直流稳压电源的输出电压、输出电流、稳压系数、波纹电压均满足技术指标。在实验教学中将设计与仿真相结合,将有利于提高学生的设计与创新应用能力。

A way of designing adjustable power supply which was based on fixed type stabilized voltage integrated circuits is presented in this paper. The process of designing power supply is simulated in Multisom software, and then circuit elements is adjust-ed by observating and testing circuit characteristics, analysising the performance of the circuit through virtual instrument and instru-ment. The experimental data show that the output voltage and output current, voltage regulation coefficient and ripple voltage of the adjustable DC regulated power supply meet the technical specifications. In experimental teaching, the combination of design and simulation will be beneficial to improve the design and innovative ability of students.
