【摘要】：平面变压器具有小体积、高功率密度以及热特性好的特点,在低压领域得到了广泛应用。该文研究了将平面变压器应用于行波管电源中,从而达到减小电源体积,提高电源功率密度的目的。结合行波管电源常用的LCLC谐振拓扑,采用部分交错绕组结构设计了一种平面变压器,并进行了电路仿真和实际测试,仿真结果与实测结果一致。采用该平面变压器的LCLC谐振变换器,输入电压为40 V,输出电压为4800 V,输出功率为295 W,开关频率为500 kHz。仿真结果与实验结果均表明,采用平面变压器,可以提高开关频率,缩小电源体积,提高功率密度,从而降低整个行波管放大器的体积和重量。
[Abstract]:Planar transformers have been widely used in low-voltage field because of their small volume, high power density and good thermal characteristics. In this paper, the application of planar transformers to TWT power supply is studied. In order to reduce the volume of power supply and improve the power density of the power supply, a plane transformer is designed based on the LCLC resonant topology, which is commonly used in TWT power supply. The simulation results are consistent with the measured results. The input voltage and output voltage of the LCLC resonant converter are 40V and 4800V respectively. The output power is 295 W and the switching frequency is 500 kHz. The simulation results and experimental results show that the switching frequency can be increased, the power supply volume can be reduced and the power density can be increased by using plane transformer. Thus reducing the volume and weight of the whole TWT amplifier.
