摘要
针对多相DC/DC变换器的控制问题,采用基于给定三角波的定频滑模控制,实现了固定的开关频率,基于多相变换器的动态模型,通过选取合适的滑模面和参数,实现了可变相数变换器单一控制器的有效控制,并进行了仿真验证和分析。
This paper deals with the control for muhiphase DC-DC converter. RTW-SMC was used to realize fixed switching frequency. The dynamic model of multiphase converter was built. By choosing an appropriate sliding surface and parameters, an effective control can be achieved in multiphase DC-DC converter using a single controller. Simulation and analysis were conducted.
