Design And Implementation Of 30-W Dc-Dc Converter With High Reliability And Temperature Characteristics For Military Applications

This paper designs and implements 30W DC-DC converters with high reliability and temperature characteristics for military applications, considering US military standards (MIL-STD). Analyzes the performance and specifications of conventional military application products and details MIL-STD items. The proposed converter is designed for guided weapons and aircraft, and it is designed with active clamp forward converter (ACFC) topology for high efficiency. To achieve high reliability, environmental impact test, device selection with excellent temperature characteristics and temperature distribution analysis are performed. The validity of the proposed ACFC for the MIL-STD specification is verified through simulation and experiments. In addition, for comparison with conventional military products, the final designed ACFC performs a performance comparison test with the IR Corporation's ATR2805S product.
