摘要

利用NI Multisim 12.0仿真软件对串联型稳压电路的稳压系数和输出电阻等参数进行测试分析,在输入电压不变时,调节电位器测试输出电压的变化范围;在输入电压变化时,计算稳压系数来判断稳压电路的稳压性能。同时通过外接可调电阻的变化,测试输出电压和输出电流的变化值,进而计算输出电阻的大小,发现虚拟测试结果与理论计算结果相吻合。仿真结果表明,将电子电路NI Multisim 12.0仿真软件引入到电子教学中,能丰富学生分析和设计电子电路的手段,有利于学生创新意识的培养和竞争能力的提升。
        The parameters such as voltage regulation coefficient and output resistance of the series-type voltage stabilizing circuit are tested and analyzed by using the NI Multisim 12.0 simulation software. The variation range of the output voltage is tested by adjusting the potentiometer when the input voltage is constant. The voltage regulation performance of the voltage regulation circuit is judged by calculating the voltage regulation coefficient when the input voltage is not constant. The variation values of the output voltage and current are tested by means of the variation of the circumscribed adjustable resistance. The value of the output resistance is calculated,and it is found that the virtual test results are consistent with the theoretical calculation results.The simulation results show that the introduction of the electronic circuit simulation software NI Multisim 12.0 to the electronic teaching can enrich students′ analysis and design means of electronic circuits,and is beneficial to the cultivation of students′innovation consciousness and improvement of competitive ability.
