Unleash the military super power

Power systems for military aircraft must tolerate extreme conditions: temperatures as low as -40°C or as high as 70°C, as well as short-term fluctuations from -55°C to 180°C; relative humidity as high as 100%; impacts reaching 60G. Difficult conditions can be tackled by using suitable materials and enclosure designs, but a system or unit's weight, size and shape are often governed by its location. These challenges are just the beginning. System reliability and availability are paramount as failures must be minimised at all times. To provide a reliable and safe power system for today's military aviators, many design teams are needed to tackle the architectural, electrical, mechanical and chemical parameters of power units. Exploiting emerging technical innovations, such as high-performance FETs, can only make life easier for designers of the future.
