| 摘 要： | 阐述了单端反激式DC/DC变换器的工作原理,在此基础上研究了其在电流连续和断续工作情况下的电路运行模式,最后在MATLAB/Simulink中对理论分析进行了建模与仿真。仿真结果表明,电路在占空比和输出电阻发生改变时,单端反激式DC/DC变换器有可能从连续工作模式下变为断续工作模式。为实际电路的设计提供了方便。

| Abstract: | The paper studies the working principle of the single-ended and flyback DC/DC converter, and studies its circuit operation mode in the case of the continuous and discontinuous current modes. At last the paper makes modeling and simulation of the theoretical analysis in the MATLAB/Simulink. The simulation results show that the circuit may change the working modes from continuous mode into discontinuous working mode when the duty ratio and output resistance is changed. This paper provides convenience for the practical circuit design of single-ended and flyback DC/DC converter. |
