HV TDSS

Curtiss-Wright has developed a high voltage turret drive stabilization system (HV TDSS) that is ideal for upgrading motion control systems intended for aiming and stabilizing turrets on mobile platforms and for rapid direct drive architectures on mobile weapons systems.

High peak power is needed to accelerate a high-inertia load, such as a turret or a weapons system, to a precise position in the shortest possible time. Many vehicles can only provide this by risking damage to the electrical systems. A solution is to use a higher current system, which needs large banks of heavy batteries and wastefully produces a lot of heat.

One way to address the peak power requirements is with an intelligent management system that can convert 28V to a higher voltage, store it, and deliver it when needed. Such a system can be easily integrated into a vehicle’s power architecture without significantly impacting SWaP-C, creating additional heat, endangering personnel, or reducing the system's overall efficiency.

The Curtiss-Wright HV TDSS addresses this need. It leverages the continuous low-voltage power available on mobile platforms to enable the high-voltage energy buffering needed for the higher voltage, shortburst peak power. It also allows a controlled flow of regenerative power back into the power architecture (e.g., energy storage or power source).

The modular solution includes

• DC/DC converter: Converts 28V battery power up to 750V and vice versa
• Energy storage module: Stores the power until needed
• High voltage motion controller: Controls and delivers the electrical power to the drive systems
• Optional load dump protector module: Protects electrical components according to MIL-STD-1275 and DEF STAN 61-5 and includes an inrush current limitation and reverse polarity protection
