“…PEBBs offer the plug-and-play architecture for various large-scale applications, providing a network with masterslave infrastructure. Several communication protocols have been proposed over the years [171], the important ones are controller area network (CAN) [175], serial real-time communications system (SERCOS) [176], motion and control ring optical (MACRO) [177], [178], [179], which is also an Ethernet communication protocol, MACRO and fiber distributed data interface (FDDI) to form power electronics system network (PESNet) [177], [180], PESNet 1.2 and 2.2 as the very two first communication protocols generated PEBBs [181], process field bus (PROFIBUS) [182], serial peripheral interface (SPI) [183], ethernet for control automation technology (EtherCAT) which interestingly most of the researchers have lately zeroed in on because of real-time capabilities, synchronization performance, fault diagnostics [184], process field net ssochronous real time (PROFINET IRT) [184], Ethernet PowerLink and Ethernet/IP [185], synchronous-converter-control-bus (SyCCo-Bus) [186], and RealSycho [187]. A good comparison between PESNet and SyCCo-Bus protocols has been presented in [188].…”

Power converters have widespread applications in automotive, renewables, and power systems. The demand for power modules with low power consumption and high efficiency has increased due to advancements in semiconductor devices. So, power converters need to be highly efficient to reduce costs associated with energy dissipation and cooling requirements. This paper discusses various active thermal control methods for high-power power converters. It covers modulation and configuration techniques, ranging from single configurations to cascaded, modular, and multilevel converters. These concepts form the basis of power electronics building blocks, particularly relevant in all-electric ship systems. Power electronics building blocks represent a This article has been accepted for publication in IEEE Access.

“…Currently, the modulation algorithm H-bridge cascade multilevel converter mainly includes: the ladder wave modulation [11], space voltage vector method [12,13] and carrier phase shift PWM method [14,15]. Ladder wave modulation is a baseband modulation method, the switching frequency is low, and conducive to high-power implementation of STATCOM, but the harmonic content of the output voltage is great, only in the case of a large number of level is high-quality output voltage obtained; In contrast, space voltage vector method with a high DC voltage utilization is easy to facilitate the digitization method, but with the increase in the number of output level, especially after more than 5 level, it is difficult to achieve, and the amount of controller operations is increased; CPS-SPWM is a multi-carrier SPWM modulation algorithm.…”

This paper mainly studies the main circuit topology, the working principle, modulation technique and control strategy of the STATCOM based on H-bridge. The STATCOM direct power control algorithm based on the virtual flux is used to control the AC side reactive power compensation, and in accordance with the principle of conservation of power, the DC side voltage imbalance factors are analyzed, and a distributed DC voltage control algorithm is also introduced. The DC side control algorithm is divided into upper and lower control parts, of which the upper control section is aimed at the average of DC side capacitor voltage of the sub-module unit for the STATCOM device, the lower control part is mainly for each sub-module DC side capacitor voltage. Finally, the control strategy is verified in a three level chain STATCOM system with VME control box as its core controller, and the experimental results show that the algorithm is feasible.

“…Phase-shift control is widely used for cascade inverters because it is easy to implement with digital controllers and it equivalently increases the switching frequency by the number of cascade units, which reduces the output voltage and current ripple [25][26][27]. For the cascade dual buck inverter, phase shift control is adopted as well.…”
