The prime purpose of the model is for the simulation studies of moreelectric aircraft power architectures at a system level; however it can be directly applied for simulation study of any other electrical power system interfacing with uncontrolled diode bridge rectifiers.

Dynamic Phasor Modeling of Various Multipulse Rectifiers and a VSI Fed by 18-Pulse Asymmetrical Autotransformer Rectifier Unit for Fast Transient Analysis

“…The 12-pulse PSR-RU discussed in [11] is taken as an example to evaluate the applicability of diode bridges DP model in the modelling of multipulse rectifier unit [18]. Fig.…”

“…Hence, u dc,lead can be restored with DPs by expanding (16) into Taylor series concerning u d,lead and u q,lead [18].…”

“…where, (22) Assuming < i dc > 0 = i dc (t), that means the 0th DP contains all information of current i dc (t) [18]. For the phase lead diode bridges, the vector of the input current is i m,lead , and it has < i m,lead > 0 = i m,lead .…”

“…Different forms to exhibit the DP model have been used in the relevant references. In [18], the DP model of a three-phase diode bridge is stated by transforming the time-domain mathematical expressions between ac and dc terminal into the DP domain. The DP models elaborated in [19]- [23] are expressed with the harmonic state-space (HSS) equations.…”

Effect of circulating current on input line current of 12‐pulse rectifier with active inter‐phase reactor

“…Installing an active or a passive auxiliary circuit at DC side of 12-pulse rectifier is an effective method of eliminating harmonics in input line current [10][11][12][13][14][15][16][17][18][19][20][21][22]. When the two bridge rectifiers are connected in parallel, an inter-phase reactor (IPR) is often used to ensure the independent operation of the two bridge rectifiers [13].…”
