“…This means that it can be used for retrofit applications, which is not possible for the one presented in [35]. It must be mentioned that in [39], a 36-PR has been proposed, which is based on 12-pulse diode rectifier with two auxiliary singlephase full wave rectifiers (ASFRs). In the structure of this 36-PR, a transformer has been used, whose rating is more than 100%.…”

In this paper, a novel pulse tripling circuit (PTC) is suggested, to upgrade a polygon autotransformer 12-pulse rectifier (12-PR) to a 36-pulse rectifier (36-PR) with a low power rating. The kVA rating of the proposed PTC is lower compared to the conventional one (about 1.57% of load power). Simulation and experimental test results show that the total harmonic distortion (THD) of the input current of the suggested 36-PR is less than 3%, which meets the IEEE 519 requirements. Also, it is shown that in comparison with other multi-pulse rectifiers (MPR), it is cost-effective, its power factor is near unity and its rating is about 24% of the load rating. Therefore, the proposed 36-PR can be considered as a practical solution for industrial applications.

“…To reduce harmonic content, DC side harmonic reduction circuits (HRCs) have been proposed in some researches [3][4][5][6][7][8][9][10][11][12][13]. The DC side HRCs, as presented in Figure 1, can be divided into three groups: PRHCs, active HRCs, and hybrid ones.…”

In [7][8][9][10][11][12], passive harmonic reduction circuits (PHRCs) have been proposed at the DC side of 12PRs to tackle the problem.…”

Here, the DC side passive harmonic reduction circuits (PHRCs) are compared from a technical and economic point of view. In researches on multipulse rectifiers (MPRs), the comparison is mainly based on different source and load conditions, especially accurate information on the amount of the source impedance is not available, which has a considerable impact on the performance of MPRs. Here, all source conditions such as voltage, frequency, and the source impedance, as well as the load power are set to be the same, in order to have an accurate and fair comparison among PHRCs at the DC side of MPRs. Some commonly-used and several DC side PHRCs are compared in terms of their operation principles, kVA rating, weight and size, power losses, input current total harmonic distortion (THD), design complexity, reliability, and cost. The results of the comparisons are used to suggest and select the most suitable PHRCs for different important industrial applications. INTRODUCTIONRectifiers are widely used in various applications like adjustable speed drives, telecommunication power supplies, high voltage direct current (HVDC) transmission, battery chargers, electric vehicles (EVs), arc furnace units, uninterruptible power supplies (UPS), aircraft converter systems, and power supplies of radar power systems. These rectifiers, are usually fed from the 3-phase system in the range of a few kW and more and have problems such as poor power factor, harmonics, AC voltage distortion, and rippled DC outputs. Many standards and recommendations have been presented, that should be considered by designers, manufacturers, and also users [1]. The designers have to simultaneously satisfy the following two requirements for any solution:• Considering the limits specified in the standards, nearly sinusoidal line currents must be obtained at a high power factor,

In this research, a novel pulse-doubling circuit (PDC) is employed to upgrade the 28-pulse rectifier to the efficient 56-pulse rectifier. The main objective of this research is to reduce the power kVA rating. In the autotransformer with a 14-phase polygon structure, the kVA rating is approximately 39.5% of the load power. Since the pulse-doubling method is utilized, the rectifier with 56 pulses has benefited from a simpler structure. With a comparison to the other rectifiers, the harmonic mitigation is the clearest feature of the proposed rectifier. According to the experimental and theoretical results, in the proposed rectifier with 56 pulses, the input current THD is less than 3%. Finally, the volume and cost of the proposed rectifier with 56 pulses show a notable reduction. In other words, the proposed rectifier is an economical choice for most sectors of the industry.
