위상배열 고출력증폭기용 고전압전원공급기(HVPS)는 다출력 소용량 진행파관(TWT)을 구동하는데 반드시 독립운용 특성을 가져야만 한다. TWT 독립운용 특성은 어느 하나의 TWT가 고장이 발생한 경우에도 부분 송신기능을 유지함으로써 관련 임무를 중단 없이 수행하는 매우 중요한 요소로 알려져 있다. 본 논문에서는 소용량 TWT들을 독립 운용하기 위한 FE 변조부를 포함한 고밀도 HVPS 하드웨어 구성 및 FPGA를 이용한 고속 독립 제어방식에 관해 기술하였다. 또한, 위상배열 고출력증폭기 운용 중 발생 가능한 고장을 모의하여 안정적으로 고장이 발생한 TWT가 독립 제어되는 시험결과를 기술하였다. In the field of electronic warfare applications, high voltage power supply(HVPS) for high power phased array transmitters must necessarily have an independent operating characteristics for driving mini TWTs. TWT independent operational characteristics, in order to run without interrupting the electronic warfare mission by maintaining the partial transmission function even when one of the TWT has occurred a failure, is known to be very important. In this paper, we describe the research on high-speed independent control system using a high-density HVPS, including FE modulators, hardware configuration and the FPGA in order to independently operate mini TWTs. Also, we have simulated some possible faults in phased array transmitters, and presents the test results to control a faulted TWT independently.

A DC-DC converter is a device that changes the voltage level through which DC flows and is generally used to convert input sources. Currently, DC-DC converters are being developed into brick-type modules whose sizes are standardized and can be installed and replaced in various applications. In addition, the importance of miniaturization through high power density is gradually emerging in order to output high power within a limited size. In order to increase power density within a limited size, it is necessary to select an optimal topology considering operating parameters such as switching frequency and current ripple, the size and number of various devices and components, and to design a circuit through precise analysis. This paper proposes an interleaved forward topology to achieve ripple reduction and miniaturization of brick DC-DC converter modules. The proposed interleaved forward topology is a topology optimized for miniaturizing brick-type modules with limited size. Planar type 2-transformer parallel structure increases power density and the primary side switches without an off-period to transfer energy to the secondary side without an off-time to maintain continuity of output. As a result, ripple voltage can be minimized and miniaturized design is possible without an output inductor that occupies a large size. In the text introduces the circuit configuration, operating principles, and main features, and explains the excellence of the proposed topology method through the actual manufactured shape and test results.
