“…• (considering only a semi-cycle), thus conducting the current in this interval [20,23,25,28,31,36,38]. In the second mode, the GRAETZ bridge rectifier is connected in series with a BOOST converter to control the output voltage and reduce the ripples of the rectangular current shape.…”

“…In this way, unidirectional rectifiers and bidirectional rectifiers can be used. In the case of a unidirectional rectifier, the modular three-phase rectifier with BOOST converter and PFC can be used [2,20,25,36]; the three-phase modular rectifier with SEPIC converter and PFC [16,23,28,29,38]; and the three-phase VIENNA rectifier with PFC [6,18,27], as well as their versions known as the three-phase Delta-switch rectifier with PFC [13,32,40] and the three-phase rectifier Star-switch with PFC [17,41]. In the case of a bidirectional rectifier, the three-phase PWM rectifier of the BOOST type with PFC can be used [26,31,34].…”

“…The first form is based on the conventional SEPIC converter but with a small modification of dividing the SEPIC inductor and capacitor by two (one on the positive and one on the negative) [12,22], as shown in Figure 7. The second way is to implement the SEPIC inductor at the input of each rectifier phase [16,19,29,30,38]. Control is also provided by two loops: the voltage loop and the current loop.…”

Hybrid Three-Phase Rectifiers with Active Power Factor Correction: A Systematic Review

et al. 2021

The hybrid three-phase rectifiers (HTR) consist of parallel associations of two rectifiers (rectifier 1 and rectifier 2), each one of them with a distinct operation, while the sum of their input currents forms a sinusoidal or multilevel waveform. In general, rectifier 1 is a GRAETZ (full bridge) (can be combined with a BOOST converter) and rectifier 2 is combined with a DC-DC converter. In this HTR contest, this paper is intended to answer some important questions about those hybrid rectifiers. To obtain the correct answers, the study is conducted as an analysis of a systematic literature review. Thus, a search was carried out in the databases, mostly IEEE and IET, and 34 papers were selected as the best corresponding to the HTR theme. It is observed that the preferred form of power distribution in unidirectional hybrid three-phase rectifiers (UHTR) is 55%Po (rectifier 1) and 45%Po (rectifier 2). For the bidirectional hybrid three-phase rectifiers (BHTR), rectifier 1 preferably takes 90% of Po and 10% of Po is processed by rectifier 2. It is also observed that the UHTR that employ the single-ended primary-inductor converter (SEPIC) or VIENNA converter topologies in rectifier 2 can present sinusoidal input currents with low total harmonic distortion (THD) and high Power Factor (PF), even successfully complying with the international standards. The same can be said about the rectifier that employs a pulse-width (PWM) converter of BOOST topology in rectifier 2. In short, the HTR are interesting because they allow using the GRAETZ full bridge topology in rectifier 1, thus taking advantage of its characteristics, being simple, robust, and reliable. At the same time, the advantages of rectifier 2, i.e., high PF and low THD, are well used. In addition, this article also points out the future direction of research that is still unexplored in the literature, thus giving opportunities for future innovation.

“…With this value, (15) and (16) solve the values of the magnitudes of apparent power. In the operation mode 2, each rectifier processes a half of the output power, thus the relations for the active powers are: The curves presented in Figure 6 were obtained by (20) and (21). They show the behavior of the active power processed for each rectifier for different operation modes.…”

This paper presents theoretical analysis and experimentation of a hybrid three-phase rectifier suitable for medium and high power applications. The hybrid rectifier is formed by the parallel connection of a threephase diode bridge rectifier cascaded by a DC-DC boost converter and a bidirectional boost-type three-phase PWM rectifier. The proposed rectifier is capable of providing sinusoidal input currents, DC output voltage control and regenerative power flow. Furthermore, the parallel association of different three-phase rectifier topologies provides power distribution, allowing the use of lower cost switches. The principle of operation, the theoretical analysis, the control scheme, simulation and experimental results from a 20-kW prototype are presented. The prototype was designed for a 380V of input voltage, 700V of output voltage and switching frequency of 10kHz.
