“…Also, the 12-pulse rectifier with the proposed PMC is superior in comparison to the 12-pulse rectifiers with the PMCs in ref. [39][40][41][42][43][44][45][46][47] both in terms of input current THD and in terms of the kVA rating. Of course, the kVA rating of 12-pulse rectifiers with PMCs in ref.…”

“…It should be noted that the proposed PMC has 2 additional diodes compared to the PMC presented in ref. [30,[39][40][41][42][43][44][45][46][47][48][49], which leads to an increase in cost, an increase in connection loss, and a decrease in efficiency. But it should be noted that the autotransformer in multi-pulse rectifiers takes the main part in cost and efficiency.…”

To improve the performance and reduce the total harmonic distortion (THD) of the autotransformer 12‐pulse rectifier, a novel pulse multiplication circuit (PMC) based on two tapped inter‐phase reactors (TIPRs) is proposed to improve performance and reduce the THD of the autotransformer 12‐pulse rectifier. The proposed rectifier includes a phase‐shifting autotransformer based on a polygon connection, two 6‐pulse diode bridge rectifiers (DBRs), and a PMC. The novel PMC consists of two TIPRs (TIPR1 and TIPR2), an auxiliary single‐phase diode bridge (including four diodes D1 to D4), and two auxiliary diodes D21 and D22, which are connected directly to the output terminal of the DBRs (DBR1 and DBR2). The simulation and experimental results confirm the high capability of the proposed PMC to reduce the harmonic distortion of the input current, so that by using the proposed PMC, the input current is almost sinusoidal and the THD of the input current is less than 3%. Also, the results show that the proposed 12‐pulse rectifier meets the standard requirements of aircraft electrical systems (DO‐160G) without the need for any input and output filters.

“…The main transformers of series-connected MPRs are mainly divided into two types, which are the isolation type and the semi-isolation type. In [13][14][15][16][17][18][19], the main transformers are isolation type. In [13,14], the structure of the transformer is delta (△)/delta (△)/star (Y) connections.…”

To improve the power density of series‐connected multi‐pulse rectifiers (MPRs), the harmonic generation principle is studied and the optimization design method for main transformers is proposed. According to the topology of series‐connected 18‐pulse rectifier, its operation waveforms are analysed, and the Fourier series of the waveforms is obtained. Based on the operation waveforms and its Fourier analysis, the principle for harmonic generation of the rectifier is researched, and the phenomenon of autotransformer cannot be applied to series‐connected MPRs is researched. According to the characteristics of the transformer, its vector graphics are analysed. Based on the vector graphics, the optimal structure of the transformer with the highest power density is obtained. The results show that the premise of the normal operation of series‐connected MPRs is the potential difference between the neutral points of different secondary windings, and only isolation/semi‐isolation transformers meet the requirement; the kilovolt‐ampere (kVA) rating of the optimal isolation type transformer is 104.6% pu, and the kVA rating of the optimal semi‐isolation type transformer is about 71.23% pu.
