“…The demand for accurate synchronization is emphasized when the parallel connection is established without or with minimal intermodule reactors, the function of which is to limit the rate of change of currents during asynchronous switchings [10]. The demonstrations, presented for example in [11] and [12], have shown that when the intermodule reactors are not used, switching pattern differences that are of the size of tens of nanoseconds and more lead to severe dynamic current imbalances between the parallel-connected modules.…”

Integrated design has become a very attractive choice for modern power electronic systems. One way to introduce modularity to integrated designs is to utilize intelligent power electronics building blocks as a base for power electronics systems. The main reason for moving toward a building-blockbased design is that the traditional centralized control structure does not provide much flexibility and reusability. A buildingblock-based design needs a distributed control scheme that sets new challenges to system design. Distributed control of building blocks requires a deterministic, real-time communication scheme and accurate synchronization. The synchronization becomes an issue especially with ring-based control topologies. In this paper, a flexible time-stamping-based synchronization scheme for a cascaded ring communication topology is proposed. Further, a communication scheme suitable for building-block-based designs is presented. The achieved synchronization accuracy is analyzed in relation to a parallel connection of power semiconductors.

“…The fourth aspect is the current sharing behavior in Si IGBT + SiC MOSFET HyS. The influence of the different delay times on the current sharing has been presented [70][71] . The mechanisms of the current sharing between Si IGBT and SiC MOSFET during the turn-off period have been discussed [72] .…”

In recent years, next-generation power semiconductor devices, represented by silicon carbide (SiC) and gallium nitride (GaN), have gradually emerged. Because wide-bandgap (WBG) devices have better electrical characteristics than those of silicon (Si) based devices, they have attracted increased attention both from academic researchers and industrial engineers. Employing WBG devices will further improve the efficiency and power density of power converters. However, the current price of WBG devices remains extremely high. Thus, some researches have focused on the hybrid utilization of WBG devices and Si-based devices to achieve a tradeoff between the performance and cost. To summarize the current research on WBG/Si hybrid applications, the issues mentioned above with representative research approaches, results, and characteristics, are systematically reviewed. Finally, the current research on WBG/Si hybrid applications and their future trends are discussed.
