摘要
以移相全桥软开关电源为研究对象,将基于能量模型的无源控制思想引入其闭环控制中,建立了一般Buck型DC/DC变换器的Euler-Lagrange平均模型;推导出移相全桥软开关DC/DC变换器无源控制策略;给出并分析了仿真结果。该方案具有运行稳定、抗干扰能力较强、控制算法简单等优点。
Taking phase-shifted full-bridge soft switched power supply as research object, introducing passivitybased control theory into its closed-loop control, the Euler-Lagrange average model of common Buck type DC/DC converter was established, the passivity-based control law of DC/DC converter was deduced, and the simulation result was analyzed. The advantages of stable running, stronger anti-interference capacity, simpler control arithmetic etc. was shown out.
