| 摘要: |
| 在开关元件平均模型法的思想基础上,提出了一种工作在连续电感电流模式下的DC-DCBoost(升压)变换器模型。考虑开关电阻、电感电阻及纹波寄生参数的影响,推导出理想与非理想传递函数。对其开环传递函数进行仿真和比较后可以发现考虑电感纹波的模型与实际更加接近,精度更高。 |

| Abstract: |
| Based on the theory of switch average model,a averaged model of DC-DC Boost converters operating in the continuous conduction mode(CCM) is proposed.Considering the resistor of switch,resistor of inductance and current ripple of inductor,we get ideal transfer function and non-ideal transfer function.After simulation and comparison of transfer functions,the model of considering current ripple of inductor is more accurate and close to the actual. |
