DAB‐based PET in MVDC traction and shipboard applications with distribution and redundant control

A Review of Power Converters for Ships Electrification

“…Alternatively, You et al [79] proposed cascaded topology for shipboard systems, in which cascaded low power Submodules (SM) are connected to operate at medium-voltage ranges, as shown in Fig. 9 (b).…”

“…Besides, they provide a cost-effective solution since they are composed of low-voltage, low-cost semiconductor technologies [86]. The MMC can be categorized based on the SM into half-bridge [80], full-bridge [79], [82], and three-level SM. In [80], an isolated configuration based on half-bridge SM is proposed, as shown in Fig.…”

A Review of DC Shipboard Microgrids—Part I: Power Architectures, Energy Storage, and Power Converters

“…The benefits of NPC are clarified in inverter section. Even though three-level converter has the advantages of low switch voltage stress, low electromagnetic interference (EMI), and good power quality [111], when it comes to medium-voltage high-power applications, semiconductor switches and diodes are exposed to considerable current stress. To fit the high power rating requirement in SMGs, a multi-phase NPC-based DC/DC converter (4000V/710V) for DC-SMGs is presented in [112].…”

“…To fit the high power rating requirement in SMGs, a multi-phase NPC-based DC/DC converter (4000V/710V) for DC-SMGs is presented in [112]. In addition, the ANPC DC/DC converter for MVDC grid is studied in [111] to achieve better thermal performance in semiconductor devices and lower losses.…”

Coordinated Control of MVDC Shipboard Microgrids with Pulsed Power Loads

“…DC/DC converters with galvanic isolation are preferred in medium voltage applications. Figure 2-5 (a)-(c) show three topologies used in marine application: input-seriesoutput-parallel (ISOP) dual active bridge (DAB) DC/DC converter [71], NPC-based DC/DC converter [72], and isolated MMC DC/DC converter (iM2DC) [73]. In these…”
