This is the fourth post in the series providing an introduction to COTS power supplies, which explains the requirements for holdup in the case of variations in the input power.
This is the fourth post in the series providing an introduction to COTS power supplies, which explains the requirements for holdup in the case of variations in the input power.
This post, the third in the series about requirements for COTS power supplies, describes tests that ensure that the equipment is properly designed to meet the environmental conditions that it may face during its service. Many of these tests are very stringent: if these demanding requirements must be met, then often a custom solution is likely to be required.
This is the second in a series describing the requirements that must be met when developing COTS power supplies. At Vicor, we manufacture a range of COTS power components as well as complete COTS power supplies that are available from our Westcor division. A key requirement is for these products to meet Mil-STD 461, which defines the EMI performance that must be achieved.
This is the first of a five-part series of blog posts by Jeff Lally, one of Vicor’s product managers, that explains some of the challenges and opportunities presented by the use of COTS products in defense applications. The series covers the most important electrical and environmental standards, and provides insight into how engineers can successfully meet military requirements with COTS components.
Defense applications can provide some of the toughest challenges for power system designers. Not only are these systems often complex and challenging electrically, but the harsh environments in which they must operate demand a robust and rugged design.
A recent article in ECN by Joshua Israelsohn, “Light UAVs serve both military and civilian missions”, describes how important it is to reduce weight to increase the performance on unmanned aerial vehicles (UAVs).
