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.

Key words： Space Travelling-Wave Tube Amplifiers (TWTAs) LCLC resonant converter Planar transformer Switching frequency
