A Fault Detection and Protection Scheme for Three-Level DC–DC Converters Based on Monitoring Flying Capacitor Voltage
TL;DR: In this paper, the three-level dc-dc converter and its derivatives can be protected against multiple faults by monitoring the flying capacitor voltage, which can not only prevent the system failure against unbalanced voltage stresses on the switches, but also provide a remedy for the system as faults occur and save the remaining components.
Journal ArticleDOI
Investigating Switching Transformers for Common Mode EMI Reduction to Remove Common Mode EMI Filters and Y-Capacitors in Flyback Converters
TL;DR: The Flyback converter can finally meet electromagnetic interference (EMI) standards without using CM EMI filters and Y-capacitors and can help quickly design and evaluate transformers in mass testing.
Journal ArticleDOI
Design and Implementation of a High Power Density Three-Level Parallel Resonant Converter for Capacitor Charging Pulsed-Power Supply
Honggang Sheng,W. Shen,Hongfang Wang,Dianbo Fu,Yunqing Pei,Xu Yang,Fei Wang,D Boroyevich,F.C. Lee,C.W. Tipton +9 more
TL;DR: In this paper, the authors describe the design and implementation of a prototype 30-kW pulsed power supply for capacitance charging, which operates at 200-kHz maximum switching frequency, which is considerably higher than the conventional practice at this power level.
Journal ArticleDOI
Investigate and Reduce Capacitive Couplings in a Flyback Adapter With a DC-Bus Filter to Reduce EMI
TL;DR: In this article, the authors investigated near-field capacitive couplings and the reduction techniques in a high power-density power adapter with a dc-bus filter, where the parasitic capacitive coupling theory is developed and parasitic coupling capacitances are experimentally extracted.
Investigation and Reduction of EMI Noise Due to the Reverse Recovery Currents of 50/60 Hz Diode Rectifiers
TL;DR: In this paper , the reverse recovery currents of the 50/60 Hz diode bridge can lead to significant electromagnetic interference (EMI) noise violating EMI standards above 150 kHz.
