Power supply systems for defence applications a review part: II power conditioner system

Defense applications require quality electrical power in the form of three phase/single phase AC, 50 Hz/400 Hz and regulated DC power in general in the form of 5/12/24/28/48 V. To full fill these requirements, power conversion systems in the form of UPS, PCS, SMPS are required to be developed. Also various applications require different servo drives for controlled and desired speed / torque applications. Hence it is important to have efficient, compact, and reliable power conversion units with high power density to supply a wide range of loads for Military systems. More and more efforts are required for better power electronic systems in terms of reliability to ensure high availability, long life, sufficient robustness, low maintenance for such applications. Wideband gap devices such as Silicon Carbide (SiC) and Gallium Nitride (GaN) devices in power electronic converters can be used to reduce the device losses in futuristic defense applications. This paper presents the over view, need and requirement, customization and design aspects of power converter systems for defense applications. Some of the case studies on recent developments of such variants of power conditioning systems are also presented in this paper.
