Power Systems for Railway Applications

Posted on 18-Aug-2016 12:00:00

Rail applications demand that equipment is able to withstand the harsh climatic, mechanical and electrical environments encountered on traction vehicles and rolling stock. Electronic equipment, from lighting through passenger information and entertainment, to control, safety & engine management systems require DC/DC power conversion and must perform safely and reliably.

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time will be mandatory to use in demonstrating conformity to the Low Voltage Directive when the current standards are withdrawn in 2019.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.

Airflow direction, Does it matter in a power system?

Posted on 28-Apr-2016 03:16:00

Does airflow direction matter in a power system? Absolutely!, well actually it depends. It depends on many factors and they all need to be considered at the beginning of the product design cycle. Before I sit down and start the 3D design, one of the first questions I ask is “what is the airflow direction within the customers system?” I also need to know what type of cooling the power supply that I am integrating requires.

Common Capacitor Types

Posted on 13-Apr-2016 14:48:00

Capacitors are used for energy storage and filtering. As there are many types of capacitors, each type has its advantages and performs best for different applications. The composition of a capacitor determines how it is used. Some commonly used capacitor types are tantalum, aluminum electrolytic, and ceramic.
