Understanding the value of power supply design verification and test
Summary
A thorough DVT can avoid problems manifesting in the field, which can tarnish the end customer’s reputation and involve significant costs to repair or service. Some power supply companies focused on a low operating cost model may need to invest more time and money in a detailed DVT. The value of detailed test reports Temperature measurements on convection-cooled power supplies are performed within an enclosure to simulate the end system conditions within which it will be mounted. So cold air blowing from an air-conditioning vent above a test bench can easily reduce readings by 10°C and severely change lifetime forecasts. This is less likely to produce issues with today’s CAD (Computer Aided Design) software, 3D modelling and the use of that data to program metal forming machinery or even additive manufacturing (3D printers) equipment.
