Hardware configuration of High-Density HVPS and High Speed independent Control method Using FPGA for Phased Array Transmitters Kang, Chun-Ho; Lee, Sung-Wook; Lee, Hong-Hak; Lee, Chang-Hoon; Byun, Gi-Sig;
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.
