DYNAMIC FLEXIBLE EXTENDED HARMONIC DOMAIN MODELING AND SIMULATION OF SWITCHED CIRCUITS

Transient analysis and simulation of switched circuits require accurate models that permit to reproduce dynamics as close as possible to real components. This paper introduces the application of a novel technique named as dynamic flexible extended harmonic domain (DFEHD) by simulating a switched circuit, i.e., an RLC circuit supplied by harmonic and interharmonic sources. The DFEHD technique is seen as a block-function whose input consists on the state-space system and as output the simulation results. The main objective of this paper is to demonstrate the simplicity of simulating linear time-periodic systems via the block-function DFEHD. The proposed case study is validated via PSCAD/EMTDC. © 2022, Politechnica University of Bucharest. All rights reserved.
