摘要
单周期控制是一种用于功率变换器的新型非线性控制策略,当输入电压发生扰动或负载快速变化情况时仅在一个周期内就可实现控制目标。将单周期控制技术控制技术应用于ZCS准谐振DC/DC变换器构成的激光电源,并通过软开关技术减小了开关损耗,减轻了电路体积。通过电路建模的方式,使用Pspice软件对电路进行了仿真。并对电源电路进行了实验研究,完成了硬件电路设计和主要电路参数的确定。实验结果证明了原理分析和设计方法的正确性。
A One-Cycle-Control switch has the ability to reject the input voltage perturbation or the load step and to realize control objective only one cycle.One-Cycle-Control technique is used in control circuit,which is worked in Buck type DC/DC quasi-resonant converter.Theoretical analysis proves that the new power supply has high performance such as high accuracy,light weight and low switching loss compared with the traditional laser power supply.There is a lot of simulation in the paper,which is acquired by the software of Pispce.And the experiment results show that the power supply of pusle laser has excellent electrical characteristic as the theoretical analysis and simulation results have proved.
