Harmonic Analysis of Single-PhaseFullBridge Rectifiers Based on FastTime Domain Method

Single-phase full bridge rectifiers areheavily usedin lowvoltage distribution system. Itistherefore essential topredict theharmonic levels these converters produce. Inthis paper, afast timedomainmethodispresented tosolve forthecurrent and voltage harmonics injected bysingle-phase diode bridge rectifiers. Themethodishighly accurate anditdoesnotsuffer from harmonictruncation errorsor aliasing effects thatexist in harmonic domainanalyses orbruteforce timedomainsimulation methods. aliasing effects. Thepaper isorganized asfollows: Section IIintroduces the modelofasingle phase diode bridge rectifier. Section IIIand IVshowhowtousetheproposed method toanalyze continuous anddiscontinuous conduction modes(4). Section V presents numerical results, andcompares computed results withthose obtained byPSCAD/EMTDCsimulation todemonstrate the validity ofthemethod.
