With the continuous improvement of the performance of the spaceborne active phased array antenna, the power supply required by the phased array antenna is developing towards low voltage and high current. The efficiency of the power supply is more stringent. This paper presents a design of a high-reliable power supply for space-borne active phased array antenna. This article introduces the composition of the phased array antenna power supply, and proposes a novel high-reliability single transistor forward interleaved parallel topology. The synchronous rectification control technology is adopted to realize the zero-voltage switch (ZVS) of the DC/DC converter, which effectively reduces the loss of the rectifier device and improves the efficiency. Secondly, the maximum current autonomous current sharing technology is used to realize parallel connection of multiple DC/DC converters. Finally, through the results of working waveforms and experimental verification of the engineering prototype, all the requirements are achieved.
