62368-1: Audio/video, information and communication technology equipment – Part 1: Safety requirements

Posted on 13-Jul-2016 14:02:16

With the convergence of information technology equipment (ITE), communication technology equipment (CTE) and audio/video equipment using common technology, cross platform architecture and use in similar environments, a new safety standard has been developed to replace the familiar 60950-1 and 60065 standards.  The new standard is hazard based and in several years time will be mandatory to use in demonstrating conformity to the Low Voltage Directive when the current standards are withdrawn in 2019.

Input Protection

Posted on 15-Jun-2016 11:57:41

Input protection is implemented in power supplies and DC/DC converters to ensure safe operation. The input fuse fitted within a power supply is not intended to be field-replaceable, it is rated such that only a catastrophic failure of the power supply will cause it to fail. It will not be cleared by an overload as the power supply will have some other form of overload protection, usually electronic. The fuse will often be soldered into the PCB rather than being a replaceable cartridge type fuse.

High Voltage Power Supply Grounding Techniques for Optimal Performance and Reliability

Posted on 01-Jun-2016 14:03:00

Ground is ground, right?  In truth, there is no ideal ground, all ground paths have inductance, resistance and noise.  Managing the various ground paths interfacing with a high voltage power supply makes the difference between a good design and a great design.

History of Switch Mode Power Supplies (SMPS)

Posted on 10-May-2016 14:30:00

I recently had lunch with a customer we’ve worked with since the late 1990s. We’ve seen a lot of change in that time and, as the main course arrived, we started talking about how power supply technology has advanced over the years. This has been most noticeable in the areas of efficiency and power density.
