| 提出了一种分析DC/DC变换电路分析方法。对该分析方法的原理和具体运用进行了详细说明。装置电路在电流连续的情况下,分别给出了DC/DC变换器的稳态工作和小信号扰动的条件下,DC/DC变换电路的输入电流、电压和输出电流、电压的关系表达式。在已有分析的基础上,借助计算机仿真软件,对所分析的DC/DC变换电路进行了开环条件下的仿真。并把使用状态平均法分析得到的结论和使用计算机仿真软件得出的仿真结果进行比较,两者的结论是完全吻合的。说明使用状态平均法对DC/DC变换电路进行分析是完全可行的。 |

| Abstract: |
| An analysis method of DC / DC converting circuit based on state averaging method is presented with its principle and application. Relation expressions between input voltage / current and output voltage / current are given for stable working condition and small signal disturbance condition respectively,and the computer - based simulation is made under open loop condition. The analytic result accords totally with the simulative result,which proves the DC / DC converting circuit analysis using state averaging method is feasible. |
