A novel passive correction approach is proposed in this paper. By adding a passive auxiliary circuit to the ac side of the rectifier with dc-side C filter, the input currents and power factor can be improved. According to distinctive configurations of the auxiliary circuits, eight low harmonic input rectifier topologies are derived. Three rectifier topologies with better comprehensive performance are deeply analyzed and compared in operation principle, auxiliary circuit design and characteristic discussion. Experimental results from the prototypes are shown to confirm the validity of the analysis and the feasibility of the proposed approach.

“…Although the PWM rectifier has near sinusoidal input currents, it also has some significant drawbacks compared to the three-phase diode rectifier: larger commutation losses, increased costs, EMI -related problems and inferior dependability. Recently, new rectifiers with a low content of superior harmonics for the input currents have been described in the works [3][4][5][6]. This paper proposes a new method for increasing the performance of these converters in such a manner as to make them technically and economically competitive with three-phase diode rectifiers with passive filters.…”

The electric energy losses as well as electromagnetic pollution of the environment by the modern electric or electronic apparatus running in a commutating regime may be reduced to minimum with the help of power electronics, field which will be well developed in the next century in order to modernize industry, transport, telecommunications, etc. The paper present a wind generator system based on a new converter configuration with a asymmetrical rectifier with near sinusoidal input currents (Asim-RNSIC), we propose a method to reduce by 15%-25% of the reactive elements (capacitors and inductances) of a asymmetrical rectifiers with near sinusoidal input currents (Asim-RNSIC). This method consists of the parallel connection of two RNSIC converters of the same type, dimensioned for half of the converted nominal power and whose entry currents are phase-shifted with an angle of 30°-40° by the correct choosing of the inductances on the AC part. Thus, it results a sufficient compensation of the type 5 current harmonics generated in the power grid when the capacitors and inductances of the two rectifiers are lowered accordingly. The converter, named Asim-RNSIC, is economically and technically more competitive compared to the three-phase six-pulse fullbridge diode rectifier with passive filters.

“…Rectifiers applying current injection contribute to the reduction of other harmonics present in input current, where the frequency of the injecting current is equal to the triple of the line frequency [8], [9]. Novel topology rectifiers, such as three-phase diode rectifiers with LC resonance in commercial frequency [10], three-phase rectifier with near sinusoidal input currents (RNSIC) have caught increasing attention in recent years [11]- [14].…”

In this paper, an optimal design method of threephase rectifier with near-sinusoidal input currents (RNSIC) is proposed. By using the proposed method, high power factor could be achieved as well as low input current harmonics, making the converter more practical. Moreover, based on the operation principle analysis of RNSIC, characteristic of the rectifier is discussed. Experimental results form three prototypes with different specifications are shown to confirm the validity of the analysis and the feasibility of the proposed optimal design method.
