“…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.

“…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.…”
