提出了一种新型的单开关升-降压式(Buck-Boost)直流变换器的电路仿真平均模型。这种模型可通过输
入参数的选择实现对Buck-Boost电路的电压控制、峰值及平均电流控制,以及对DCM-CCM工作方式的统一。它
是一种实用的仿真模型,可方便地进行稳态和动态分析。在保证准确的基础上,大幅度提高了仿真的速度,通常比
用实际器件开关电路的仿真速度提高两到三个数量级。
-A novel average model for single switch Buck-Boost DC/DC converter has been given. Voltage control
mode, peak current control mode and average current control mode can be varied easily by changing the parameter of the
average model. This model can unify continuous conduction mode (CCM) and discontinuous conduction mode (DCM). It
can be used to do static and dynamic circuit analysis. By using this average model the simulation speed can be improved by
2~3 order comparing with the using of switched model.
