Leland Teschler • Executive Editor lteschler@wtwhmedia.com On Twitter @ DW_LeeTeschler The latest figures from the National Fire Protection Association show that only about 20% of all vehicle fires arise from problems in the vehicle electrical system—most fires have something to do with the fuel system. Seeing as electric vehicles will do away with problematic petrol, […]

Why is it vital to include power factor in ac-dc efficiency measurements?
Ron Stull of CUI explains what power factor is, how it affects efficiency calculations and how it is measured With today’s concentration on energy savings, design engineers need to know with increasing accuracy what their ac-dc power converter efficiency is. Measuring the ratio of output power to input power is simple for dc-dc converters, but […]
Why isolated digital inputs are replacing optocouplers in up to 300V systems
by Anant Kamath, Texas Instruments Isolation is a means of preventing DC and unwanted AC currents between two parts of a system while allowing signal and power transfer between those two parts. Isolated voltage detection is used in many industrial applications, including protection relays, power station automation, high-voltage battery management, telecom power supplies, home automation, […]
Power-supply noise, Part 2
Part 1 looked at the basics of noise, especially concerning power supplies. There are two noise sources which are not as obvious to many engineers as noise that results from the switching action of the power supply: differential mode noise and common-mode noise. These two noise modes have different causes and thus different solutions Q: […]
