“…Generally speaking, it means that abnormalities can be detected immediately after the fault occurs, diagnosing and repairing in a short time. Compared with the relevant mentioned loss model, from a period of time can reduce the total output power reduction, improving the efficiency of reducing energy consumption [86]. For the development of related detection systems, improving punctuality and accuracy will play a significant role in the future research.…”

In recent years, the world has been paying more and more attention to the power electronics converter in the power system. The power electronics converter has made great development in its own structure and control strategy, but there are still concerns of significant energy consumption and insufficient energy saving in many fields of application, the purpose of this paper is to let researchers grasp the current situation of the power electronics converter research and advance the development of the industry. Firstly, we review and evaluate some relevant methods that can evaluate the energy consumption of power electronic converters and introduce several cases of improving the topology in order to achieve energy saving. Afterwards, we introduce and summarize the development and application of power electronic converters in specific scenarios. The review and discussion presented in this paper concludes with some limitations and concerns in the current development of power electronics converters.

“…In order to accomplish a modular power converter, different proposals can be found in the literature using basic power cells [4], [5] to interface with the power system. This power cell is known as Power Electronics Building Block (PEBB) [5] and has to be controlled according to the desired power converter topology. Therefore, a distributed control system has to be developed in order to achieve a proper behavior of the modular power converter.…”

This paper proposes a distributed control alternative for modular power converters. The focus is on the use of singlephase power units with embedded control capabilities, namely intelligent Power Electronics Building Block (iPEBB) for power conversion in hybrid DC/AC microgrids. The distributed control is achieved by the use of a versatile controller inside each iPEBB, so that they can operate independently by controlling their own voltage(s)/current(s). For the management of the entire system, a central controller is integrated into the control scheme. The central controller is in charge of the application-level control of the modular power converter, so that it determines the role of each iPEBB and commands the references to achieve the control goals. As a demonstration of the proposed approach, the control of a 4-wire 4-leg STATCOM using 4 independent power units is shown in this paper. For the implementation of the iPEBB control system, two different approaches are evaluated: Proportional-Resonant (PR) and Repetitive Control (RC) alternatives. Analysis is done using direct discrete design. Different simulations as well as experimental results are performed in order to validate the proposed system. The study considers communication delays between the central controller and the iPEBB as well as internal reconstruction of the reference from the central controller command.

In this paper, power loss and cost models of power electronic converters based on converter ratings and datasheet information are presented. These models aid in creating rapid prototypes which facilitate the component selection process. Through rapid prototyping, users can estimate power loss and cost which are essential in design decisions. The proposed approach treats main power electronic components of a converter as building blocks that can be arranged to obtain multiple topologies to facilitate rapid prototyping. In order to get system-level power loss and cost models, two processes are implemented. The first process automatically provides minimum power loss or cost estimates and identifies components for specific applications and ratings; the second process estimates power losses and costs of each component of interest as well as the whole system. Two examples are used to illustrate the proposed approaches-boost and buck converters in continuous conduction mode. Achieved cost and loss estimates are over 93% accurate when compared to measured losses and real cost data. This research presents derivations of the proposed models, experimental validation of the models and demonstration of a user friendly interface that integrates all the models. Tools presented in this paper are expected to be very useful for practicing engineers, designers, and researchers, and are flexible and adaptable with changing or new technologies and varying component prices.
