摘要
从单端正激逆变器和硬开关存在的不足,提出了用两个单端正激逆变器并联,用软开关交错控制方法。交错并联逆变器即能使输出功率密度增加又能使电压频率增加一倍,减小了装置体积和输出纹波,同时降低了开关管的损耗。通过仿真和试验该控制该方法能达到预期效果,控制系统能稳定可靠地运行。
The approach of a parallel double single-ended forward inverter and an interleaving control of a soft switching are presented based on the shortage of the single-ended forward inverter and the forced-switching in this paper.An interleaving parallel inverter can not only increase the output power intensity ,double the voltage frequency ,decrease the device volume and the output ripple,trot also reduce the loss of the switch components.The simulation and experiment shows that the control approach can carry our purpose expected ,and the control system runs stably and reliably.
