High slew rate power supplies for support of large pulsed loads

Emerging high power electric weapons and sensors create challenges for future naval power systems. To address these large transient loads, energy storage systems must have high energy and power density and be capable of high slew rates - rapidly transitioning from supplying to absorbing energy. These energy storage systems have been conceived to support specialized mission loads within the ship´s electrical power system. This paper presents two rotating machine concepts that combine inertial energy storage and transient power capability to mitigate the impact of these transient loads on the power system. These machines are key elements of modular, multi-mode power supplies that can be tailored to range of naval power system applications.
