摘要

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 are widely used in low-voltage applications because of the advantages of low profile, high power density and excellent thermal characteristics. This paper applies the planar transformer for power supplies to Travelling-Wave Tube Amplifiers (TWTAs). Based on the LCLC topology, which is always used in TWTAs, a planar transformer with an interleaved structure is designed. In addition, the experimental results are in accordance with the simulation results. The input voltage of the converter is 40 V, the output voltage is 4800 V, the output power is 295 W and the switching frequency is 500 kHz. Conclusions can be drawn that with the planar transformers, the switching frequency can be increased and the volume of the power supplies can be reduced.
