“…A modulation scheme such as the SS-I with no switch-switch commutations is recommended in this case. It should be noticed that the switching performance of the RB-IGBT has been improved in recent years by adopting a deep boron diffusion technique and a thin wafer technology [23], [33], [34]. With electron irradiation, the carrier lifetime can be shortened to reduce the reverse recovery current [23].…”

The three-phase buck-type rectifier features a stepdown ac-dc conversion function, smaller filter size, inrush current limiting capability, and potential for high efficiency, where its switching loss is dependent on the modulation scheme and the specific semiconductors used. In this paper, three different device combinations are compared through experiments on their switching characteristics for the buck rectifier application. It is shown that the switching performance of two series-connected devices becomes worse than a single device due to the superposition of the nonideal semiconductor characteristics. Moreover, the switching loss in the commutation between two switches is usually higher than the one in the commutation between a switch and the freewheeling diode. Taking into consideration both types of commutations, the switching loss of the buck rectifier is then modeled and the analytical equations are derived for four space vector modulation schemes. According to the analysis, each modulation scheme has its own field for high-efficiency application. The most advantageous modulation scheme is identified in this paper for each of the device combinations investigated.Index Terms-Buck rectifier, high efficiency, modulation, reverse blocking insulated-gate bipolar transistor (IGBT).

“…14, the RB-IGBT has longer tail current and higher voltage spike than the other two kinds of switches. It is because of the long carrier lifetime of RB-IGBT and the heavily doped p+ layer on its collector [16] [17]. There is a trade-off between the conduction loss and switching speed [16].…”

“…It is obvious that the characteristics of the diode influence the switching waveforms much. In the case of RB-IGBT, there is much larger current spike because it behaves like a Si PIN diode under reverse voltage with more extra charge than the Si soft-recovery diode [15][16][17][18]. Comparing the switching waveforms in Fig.…”

The three-phase buck-type rectifier has advantages as front-end converter for high efficiency power supplies in telecommunication and data centers. In this paper, the different commutation types of a three-phase buck rectifier with a freewheeling diode are analyzed through experiments using different semiconductor devices. Further, the switching loss of the converter is modeled and calculated for four space vector modulation schemes. It is shown that when the switches include minority carrier devices, such as Si PiN diode, IGBT and Reverse Blocking IGBT (RB-IGBT), more switching loss will occur in the commutation between two switches than between a switch and the freewheeling diode. This difference can be reduced if majority carrier devices, such as SiC Schottky diodes, are used in series with the switches. The modulator can be arranged to eliminate the specific transition which has the most switching loss. According to the analysis, each modulation scheme has its own field for high efficiency application. The advantageous modulation scheme is given for different device combinations in this paper.Index Terms-Three-phase buck rectifier, high-efficiency PWM, device comparison

“…Another issue that puts the CSC step-aside is the better control and efficiency of VSC. However, the development of reverse blocking IGBT (RBIGBT) semiconductor devices will improve the performance of the CSC, since the RBIGBT has lower power losses rather than IGBT with series diode [1], [2]. Researches have shown certain advantages of CSC.…”

In this work it is presented a novel topology of Current Source Converter (CSC) that allows to control two single-phase AC converters independently sharing the same DC-bus, with the advantage of having a reduced number of conducting switches, less switching and a lower DC-bus current. A conventional double single-phase CSC that uses the same DCbus needs to have two two-legs (H-bridge) converters connected in series, which means that it will always have four conducting switches. The new topology proposed allows to generate any two AC output currents with the same number of switches, however having always only three conducting switches in a switching period, representing 25% less conducting losses comparing on the equivalent conventional double single-phase CSC. It is also presented a Scalar Pulse Width Modulation (SPWM) and Space Vector Modulation (SVM) to control the converters with switching optimization, which reduces the switching losses. Details of topology, control strategy and modulation are presented. Simulation results are provided to validate the theoretical approach.
