Why is it vital to include power factor in ac-dc efficiency measurements?

October 25, 2018 By Aimee Kalnoskas Leave a Comment

power factor

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

April 16, 2018 By Aimee Kalnoskas Leave a Comment

isolated digital inputs

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

January 26, 2018 By Bill Schweber 1 Comment

power-supply noise

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: […]

Six considerations for better circuit protection

October 2, 2017 By Chris Francis Leave a Comment

In an electronic system where the power source can be connected the wrong way round, protection should be considered to prevent damage to the circuitry. Most electronic circuits don’t like the power supply being reversed. However, there are other eventualities you could protect your circuit or system from temperature, humidity, excess current or excess loading, […]
