Flyback Transformer Modelling

source: Kocaeli university Kocaeli Turkey, EPCI e-Symposium Abstract: Providing the required load power using Switch Mode Power Supplies (SMPS), leads to smaller and more efficient converters. Flyback converter is one of the most famous topologies in use. Flyback converter is equivalent to buck-boost converter with the inductor split to form a transformer. The operating principle […]

Supercapacitor Degradation and Reliability

source: Brno University of Technology CEITEC, EPCI e-Symposium Abstract: Degradation of supercapacitor (SC) is analyzed by accelerated aging test. Evolution of SC parameters is determined before the aging test, and during up to 8 x 105 cycles of both 75% and 100% energy cycling. Capacitance fading, equivalent series resistance (ESR) increase, and leakage current trend […]

Use LT SPICE to analyze input filters

source: EDN article Kenneth Wyatt -December 28, 2016 EMC engineers are often called on to design low-pass filters for client projects, which is usually required to meet radiated susceptibility tests. While the most common radiated-immunity standard (IEC/EN 61000-4-3) requires testing from 80 MHz to 1000 MHz, this case study required immunity from a nearby 50 […]
