摘要
针对传统开关电源中损耗较大,超调量较大,动态性能较差等问题,提出了基于DSP的全桥软开关技术。通过Matlab仿真结果表明模糊自适应PID控制算法比传统PID控制算法在超调量、调节时间、动态特性等性能上具有优越性。
The traditional switching power supply has some problems, such as big loss and overshoot, bad dynamic performance and so on. In this paper, we propose a new full-bridge soft-switching technology based on DSP in order to overcome these problems. The simulation results under Matlab show that fuzzy adaptive PID arithmetic has better capability in overshoot, adjusting time and dynamic performance compared with the traditional arithmetic.
