摘要
针对传统的双管正激变换器在实际应用中存在动态特性弱的缺点,提出了基于单周期控制的双管正激变换器。利用单周期控制技术可以使开关变量在一个开关周期中精确地跟随给定值这个特性,将单周期控制技术运用到双管正激变换器中,就系统在实际运行中较易出现的电压、负载及给定等参数变化的几种状况分别进行研究,研究结果验证了基于单周期控制的双管正激变换器具有良好的动、静态特性及较强的抗干扰能力。
To the problem that double-barreled forward converter using double switch structure with low switching voltage stress,inner resistance to bridge at arm ability,higher reliability has the shortcomings of weal dynamic characteristics,the double-barreled forward converter based on a single cycle control is proposed.Using a single cycle control in double-barreled forward converter can make the switch variables follow accurately control reference on a switch cycle.The single cycle control technique is used into double-barreled forward converter to research several cases such as the voltage,load and given parameters change in practical operation.Simulation results show that the single cycle control technology had good dynamic and static characteristics and strong anti-interference ability.
