摘　　要：针对部分便携式设备中升压变换器输出电压谐波不理想的情况,提出了一种新型的1+D非隔离式变换器,并对该拓扑结构非线性行为了进行分析研究。为控制其混沌行为采用了基于时间连续延迟反馈方法的混沌控制技术,通过搭建Simplorer仿真模型获得仿真结果,验证了在该变换器闭环系统中采用延迟反馈控制策略可有效抑制其混沌现象,同时使负载瞬态响应得到改善。For some portable devices currently, the output voltage harmonics of its boost converter are not ideal, this paper puts forward a new type of I ＋ D non-isolated converter and analyses its non-linear working condition, the chaos control techniques based on continuous time delay feedback method is adopted to avoid the chaotic behavior. with a simulation results come from the simulation model setted up by Simplorer, it is verified that this converter con- dueted in a closed-loop system can restrain the chaotic phenomena effectively by using the delay feedback control strategy, at the same time, improve the load transient response.
