摘要
对工作于电流连续模式下的电压反馈型双管正激变换器,在一定的假设前提下建立小信号模型来研究变压器一次绕组和二次绕组匝数比不同时的非线性。利用仿真软件MATLAB/Simulink,建立仿真模型进行计算机仿真,得到滤波电感电流波形,观察到改变变压器匝数比存在非线性现象,验证了理论分析结果。
For a voltage-fed two switch forward converter in continuous-conduction mode, under some hypothesis establishing a small signal model analyse nonlinear based on different turns ratio between primary and secondary of the tranducer. Simulation mode and simulations were created and carried out in MATLAB/Simulink. According to the time-domain waveforms of the inductor current, observe nonlinear phenomenon while change the turns ratio verify the results of theoretical analysis.
