Varistors ARE viable for surge protection
by Patrik Kalbermatten, KEMET Protecting sensitive electronic equipment against transient voltages in the form of surges that may be either circuit emanating from relays or motors, or significant ESD events such as lightning strikes, is a vital part of equipment design. Several technologies exist to protect sensitive electronic circuitry from voltage surges, including gas discharge […]
Understanding the electromagnetics of real capacitors
by Asem Elshimi, Design Engineer, IoT Wireless Solutions, Silicon Labs Confession: For the longest time, up to my senior year in electrical engineering school, I thought you could find a capacitor on its own. I had such a boundless imagination to think that you could find a circuit element that is purely capacitive in behavior […]

When you don’t fuse the neutral wire
By the Power Guy, TDK-Lambda AC-DC power supplies for the medical market have long been not only safety certified to the IEC 60601-1 medical standard, but also to the industrial IEC 60950-1/IEC 62368-1 standards. Dual certification reduces the number of individual model numbers that must be produced and stocked; this practice improves production efficiency and […]
Single-stage quasi-resonant flyback controller drives LEDs
Infineon Technologies AG releases a new LED driver IC to its XDP portfolio. The XDPL8210 is a constant current flyback IC with a high power factor and primary-side regulation.
