Research on the reliability of phased array radar power supply system based on modular parallel redundancy technology

The reliable operation of the power system is the necessary conditions for the entire phased array array to work ordinarily. With the rapid development of power electronics technology, modularization, automatic current sharing and parallel connection are achieved for power converters, making parallel redundant systems available. This article studies the application of parallel redundancy in phased array power supply systems. Taking the phased array power supply in the THAAD system as an example, a reliability analysis model is established to explore the reliability improvement of phased array power supply systems by parallel redundancy.
