In this paper, a thorough analysis is carried out in order to achieve an optimal design of a forty-four pulse rectifier. In this study, a novel Multi-phase Shifting Autotransformer (MPSA) is introduced, discussed, simulated and implemented to forty-four pulse rectifier with acceptable power rates. Accordingly, the main purpose of the paper is focused on the power kVA rating reduction for power quality applications. It provides a more economical solution to achieve harmonic mitigation in electric power systems as compared with other rectifiers. The simulation and experimental results show that the input current THD is less than 3% using the proposed topology. The results indicate a significant reduction in the total cost and volume of the proposed forty-four pulse configuration in comparison with similar configurations. Also, it is shown that the proposed converter rating is about 42% of the DC load power. INDEX TERMS Forty-four pulse rectifier, multi-phase shifting autotransformer (MPSA), total harmonic distortion (THD).

“…The proposed 36-pulse diode rectifier contains two three-phase diode-bridge rectifiers, the phase-shifting angle of the phase-shift transformer should be π/6 from the viewpoint of eliminating 5th and 7th harmonics [22]. As discussed in [23], when the phase-shifting angle is π/6, the winding configuration of delta-connected autotransformer shown in Figure 2a is the simplest and the delta-connected autotransformer has the least kVA rating. Figure 2b shows the phasor diagram of delta-connected autotransformer.…”

This paper proposes a simple 36-pulse diode rectifier with an unconventional interphase reactor (IPR) and single-phase full-wave rectifier (SFR). The primary winding of the unconventional IPR is double tapped and the secondary winding is connected with SFR. The operation mode of the unconventional IPR is analyzed, and the optimal tap ratio and turn ratio of the unconventional IPR are designed from both viewpoints of input line current and load voltage. With the optimal parameters of the unconventional IPR, the proposed rectifier extends the conventional 24-pulse rectifier operation to 36-pulse operation and draws near sinusoidal input line currents, the total harmonic distortion (THD) of which is about 5.035%. The kVA rating of the unconventional IPR is about 2.6% of the output power. Compared with the conventional 36-pulse rectifier with triple-tapped IPR, the proposed 36-pulse rectifier is easy and simple to implement instead of using control circuits. Experiment results are provided to verify the theoretical analysis.

“…Due to the switching of power devices in three-phase inverters, the harmonics are generated and when these converters are integrated with system networks, the power quality of the system is affected. In order to reduce these harmonics, a comparative analysis is made between conventional 150, 180, 120 modes for SAB3 [9][10] with 14 vector groups of transformer as shown in Table 1. Figure 1 shows the SAB3 topology.…”

Background/objectives: This research study compares the performance of a three-phase single active bridge DC-DC converter with several operating modes along with vector groups in order to present the importance and applications of transformer vector groups in the electrical network system. Methods/statistical analysis: In order to analyze and compare the operating characteristics of three-phase single active bridge converter with vector groups of transformer. Initially, we made a detailed study of vector groups of transformers through literature review. Then the development of simulation model of three-phase single active bridge DC-DC converter with transformer vector groups while operating with different operating modes of three-phase inverter by using MATLAB/SIMULINK software was made. Findings: We investigated Total Harmonic Distortion (THD) in terms of voltage and current waveforms with both resistive and inductive load of SAB3 converter with the different transformer vector group while operating with different modes of conduction, i.e., 120, 150, and 180. Improvements: Undoubtedly, today's world is moving towards replacing fossil fuels with renewable energy resources. Three-phase single active bridge DC-DC converters are widely advantageous. From the simulated results, it is clear that at 150-operating mode, the SAB3 generated fewer harmonics in terms of voltage and current for both resistive and inductive load as compared to other operating modes.
