Charging High Capacitance

Monday, 5 February, 2024

Power distribution units (PDUs) for military applications have several useful features for monitoring and controlling power paths to devices in the system. One useful feature is the adjustable current limit, which can also be used during channel startup to provide a monotonic voltage ramp to a capacitance inside the downstream Line Replaceable Unit (LRU). This is done by setting a current limit value that is lower than that required for the continuous LRU load. By charging this capacitance with a constant-current source, the voltage ramp to the LRU can be set to a slower voltage ramp, averting high inrush currents that are common with switching into a capacitance.... read more

MIL-STD-704: A Challenging Standard for Airborne Applications

Tuesday, 3 May, 2022

MIL-STD-704 is an Aircraft Electrical Power Military Standard that defines a standardized power interface between a military aircraft and its equipment. The purpose of this standard is to ensure compatibility between the aircraft power system (including external power) and the utilization equipment (with connected power supplies). A power supply running directly from a generator, or its AC/DC rectifier must be able to handle the various transients from these “dirty” power sources.... read more

Military-Grade PDUs: The Advantage of Customized Units & Flexible Design

Thursday, 2 June, 2022

PDU devices serve as a ‘circuit breaker’ to protect expensive and sensitive loads designed into the system. Such loads may include computers, displays, control devices, sensors, and weapons systems. Like the circuit breaker in homes, a PDU is a necessary tool to protect against current inrush or spikes, short circuit conditions, and other electronic maladies. In today’s market, power management devices, such as PDUs, may be referred to as circuit breakers, power distribution units (PDU), remote power control (RPC), and other trade names. PDUs can come in many different shapes and sizes based on the requirements of the military system, but not all are designed for use in a military or aerospace environment.... read more

The Next Generation of Combat Vehicles

Monday, 1 May, 2023

Autonomous vehicles serve in frontline combat. The Robotic Combat Vehicle (RCV) is being developed as part of the Army’s Next Generation Combat Vehicle (NGCV) family of vehicles: light, medium and heavy. The Army reportedly envisions employing RCVs as “scouts” and “escorts” for manned fighting vehicles to deter ambushes and guard the flanks of mechanized formations, marking a significant shift in the way we approach warfare.RCVs are intended to be controlled by operators riding in NGCVs, but the Army hopes that improved ground navigation technology and artificial intelligence (AI) might eventually permit a single operator to control multiple RCVs or for RCVs to operate in a more autonomous mode.... read more

Three Phase Power - Supporting Larger Loads

Tuesday, 4 October, 2022

Alternating current (AC) power supply can be classified into single-phase and three-phase sources. Knowing the difference can help us determine when and where to use which. Requirements in airborne and ground applications utilizing AC sources of supply are becoming more frequent. In some cases, the traditional 28VDC direct current (DC) bus is at maximum current capacity and is not available, especially for higher power applications. The AC bus is often readily available for use and makes sense for upgrade and modernization programs to enhance capability on a platform.... read more
