A novel reliability prediction with input transients for an LLC converter

Frontiers in Energy Research, 2022
Utility applications demand highly reliable power converters to match market quality needs. The classical reliability prediction methods do not account for the sudden transients involved with the power converter.

Single-Event Upset Analysis and Protection in High Speed Circuits [PDF]

, 2006
The effect of single-event transients (SETs) (at a combinational node of a design) on the system reliability is becoming a big concern for ICs manufactured using advanced technologies. An SET at a node of combinational part may cause a transient pulse at

Low-frequency Oscillation Damping Control for Large-scale Power System with Simplified Virtual Synchronous Machine

, 2021
This study focuses on a virtual synchronous machine (VSM) based on voltage source converters to mimic the behavior of synchronous machines (SMs) and improve the damping ratio of the power system. The VSM model is simplified according to some assumptions (

Modeling of grain-oriented Si-steel and amorphous alloy iron core under ferroresonance using Jiles–Atherton hysteresis method

AIP Advances, 2018
Amorphous alloy is increasingly widely used in the iron core of power transformer due to its excellent low loss performance. However, its potential harm to the power system is not fully studied during the electromagnetic transients of the transformer ...

Prony Analysis for Power System Transient Harmonics [PDF]

EURASIP Journal on Advances in Signal Processing, 2007
Proliferation of nonlinear loads in power systems has increased harmonic pollution and deteriorated power quality. Not required to have prior knowledge of existing harmonics, Prony analysis detects frequencies, magnitudes, phases, and especially damping factors of exponential decaying or growing transient harmonics.

The use of real time digital simulation and hardware in the loop to de-risk novel control algorithms

, 2011
Low power demonstrators are commonly used to validate novel control algorithms. However, the response of the demonstrator to network transients and faults is often unexplored. The importance of this work has, in the past, justified facilities such as the
