摘要
在模拟电子技术实验教学中,OCL推挽功率放大器是个重要的实验项目。多年来,OCL推挽功率放大电路的实验结果一直不理想,由于大电压大电流,测试过程中时常烧坏电路。为此采用Multisim软件对OCL推挽功率放大电路进行了仿真研究。首先构建了OCL推挽功率放大电路,并理论上进行分析与计算,然后对OCL推挽功率放大电路的静态特性和动态特性进行了测试,最后主要从功率和效率方面比较了仿真结果和理论结果,并对误差的原因进行分析。从仿真结果来看,可以取得较为理想的仿真结果。
It is one of the most important experiment items for OCL push-pull power amplifier in the Analog Electronic Technology experimental teaching practice. For many years, the experiment result for OCL push-pull power amplifier has not been so ideal.Unfortunately, the testing circuit board damage occurs occasionally due to high voltage and large current. In this paper, a simulation about OCL push-pull power amplifier based on Multisim is proposed. Firstly, the OCL push-pull power amplifier circuit is constructed, then analysis and calculation has been conducted theoretically. Secondly, the static and dynamical characteristics of this OCL push-pull power amplifier is tested in Multisim respectively. Last but important, the comparison between simulation result and theoretical result mainly from the aspects of power and efficiency is presented, and the error cause is analyzed. From the simulation, the result is rather ideal.
