A highly reliable electrical power system has become an important consideration for air vehicles due to the integration of fly-by-wire technology. Redundancy is often used to improve the reliability of the overall system performance; however, a well defined design approach is needed for selecting where and how much redundancy is required to improve the system performance. Redundant configurations are often products of engineering judgement based on experience rather than an analytical process. This paper presents a top down design example of a highly reliable electrical power system. The approach presented provides a methodology and guidelines for designing and evaluating redundant systems. The approach also provides justifications of how a specific design is derived and why the system is selected as the most desirable system. An example is given in which cross-strapping was investigated to improve the electrical system reliability. The system configuration was optimized for maximum reliability using analytical tools. This paper also discusses the modes and effects of the power components which provides guidelines for selecting the most suitable product from manufacturers.
