“…As far as the price of SiC devices is concerned, if all six switching devices in the ANPC topology are replaced with SiC devices, the high cost will limit the widespread application of such products. Considering this problem, many studies have proposed hybrid applications of SiC and silicon (Si) devices, that is, only some of the devices in a system or topology are replaced with SiC devices [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. In [5], a Si CSI (current source inverter)/SiC VSI (voltage source inverter) series inverter system was proposed.…”

“…This hybrid topology can increase efficiency by 66%. In addition, based on the diversity of ANPC topology commutation modes, various hybrid SiC and Si configuration schemes have also been proposed [8][9][10][11][12][13][14][15][16][17][18][19]. In [8][9][10][11], the outer tubes connected to the bus and clamp tubes in the ANPC topology were replaced by SiC devices.…”

“…The efficiency of this SiC and Si ANPC topology under different modulation strategies was compared in [12]. In [13][14][15][16][17][18][19], the two tubes in the ANPC topology, except the outer tubes connected to the bus and clamp tubes, were replaced by SiC devices. In [13][14][15], specific SPWM (sinusoidal pulse width modulation) modulation strategies were applied to concentrate switching losses on SiC devices to achieve high efficiency and high power density.…”

Silicon carbide (SiC) devices have excellent performance, such as higher switching frequency and lower switching loss compared with traditional silicon (Si) devices. The application of SiC devices in inverters can achieve higher efficiency and power density. In recent years, the production process of SiC devices has become more mature, but the cost is still several times that of traditional Si devices. In order to balance cost and efficiency, replacing only some of the Si devices with SiC devices in a topology is a better choice. This paper proposed a high-efficiency hybrid active neutral point clamped (ANPC) three-level inverter which has only two SiC devices and the other devices are Si devices. A specific modulation strategy was applied to concentrate switching losses on the SiC devices and reduce the on-state loss through parallel operation during freewheeling intervals. Theoretical efficiency curves and experimental verification of the proposed hybrid scheme with Si-only and SiC-only schemes were carried out.

Compared with traditional silicon (Si) power devices, silicon carbide (SiC) devices have attracted extensive attention due to their excellent characteristics. In recent years, the manufacturing process of SiC devices has become more mature, but the cost is still high. Therefore, replacing only some of the Si devices with SiC devices in a topology is a better choice to achieve higher system efficiency while considering costs. This paper studies the hybrid configuration schemes consisting of two SiC devices and four Si devices (2SiC&4Si) in ANPC three-level inverter. Two hybrid 2SiC&4Si topologies are proposed. In order to make full use of the low switching loss characteristics of SiC devices in hybrid topologies, specific modulation strategies are applied to concentrate switching losses on SiC devices. Based on the 2SiC&4Si hybrid ANPC topologies, three efficient SiC&Si hybrid configuration schemes are derived. In this paper, the theoretical comparison and experimental verification of the efficiency and loss distribution of the three hybrid schemes are carried out. INDEX TERMS SiC&Si hybrid configuration, ANPC, loss analysis.
