“…Control method used in presented PoC is the Single Phase Shift Modulation (SPSM). As depicted in Figure 6, control algorithm consists of two main modules: The calculation of the appropriate phase shift in the range from 0 to 2 Pi is discussed in [50]. Then it goes to the modulator block in which the classic SPSM control system [51] is implemented, selected for this implementation due to its simplicity and good performance characteristics in dynamic states.…”

This paper focuses on two key technical concepts, which may have a tremendous impact on future generations of power electronic converters: the Power Electronic Building Block (PEBB) concept, and the 5G/6G wireless data transfer. It is expected that these two trends may induce development of new cognitive of power electronic converters: Power Electronics 4.0. To investigate this concept, a Proof of Concept (PoC) of PEBB-based power converter integrated with a 5G network, was designed and tested. Study confirmed that power converter assembled from PEBB modules can compete with state-of-the-art devices. Moreover, test results indicates that several challenges related to PEBB and integration of power electronic equipment with 5G network has to be resolved, to enable growth of augmented power electronic converters, especially if wireless data transfer is meant for communication between PEBB modules.

“…An isolated power conversion system is essential to achieve voltage transformation and galvanic isolation in the MVDC distributed system, just like the conventional ac power transformer in ac distribution. Owing to some remarkable advantages, for example, high power density, bidirectional power flow and high efficiency [6][7][8][9][10], DC transformer (DCT) is proposed. It is integrated by the power electronic converters and high-frequency transformers (HFTs).…”

DC transformer (DCT) which is composed of dual active bridge (DAB) converters, is capable of fulfiling high-ratio voltage conversion between the medium-voltage dc distribution and low-voltage dc distribution. A model predictive control (MPC) strategy was proposed for the DAB-DCT to improve dynamic performance and achieve a proper power distribution, considering the bidirectional power of DCT. The traditional voltage closed-loop control scheme with the single-phase shift (SPS) and the MPC scheme with SPS are compared on a downscale DAB-DCT laboratory prototype, using PowerPC P2020 + FPGA_6SL X45 as the core controller. The excellent dynamic characteristics of DCT with proposed MPC strategy is verified by extensive experimental results.
