基于Multisim的功率放大电路仿真分析
资料介绍
采用Multisim软件仿真的方法,对乙类互补对称放大电路进行仿真分析,通过分析电路负载的输出波形观察功放中容易出现的交越失真,在两个三极管的基极串联了两个二极管后,提供了偏置电压把静态工作点设置得比截止点稍微高一些,使放大器工作在甲乙类放大状态,有效消除了交越失真。经过仿真和分析表明,乙类功率放大器是实现功放小型化、高效率、高功放的重要途径。
In this paper,the Multisim software simulation method is used to simulate and analyze the class B complementary symmetrical amplifier circuit.Through analyzing the output waveform of the circuit load,the crossover distortion easily occurred in the power amplifier is observed.After two diodes are connected in series to the bases of the two triodes,the bias voltage is provided to set the static operating point slightly higher than the cutoff point,so that the amplifier operates in the class A and B amplification state,effectively eliminating the crossover distortion.Simulation and analysis show that Class B power amplifier is an important way to realize miniaturization,high efficiency and high power amplifier.
