Nov 29, 2020 · Finally, a three-phase 6kW scaled-down laboratory system is established to verify its effectiveness. This paper introduces the characteristics of a novel single-stage power electronic transformer (PET) based on isolated modular multilevel converter (I-M2C).

Jul 27, 2020 · One MFT is shared by three-phase MMC arms, which contributes to the compact structure and reduced cost of PET. The operating principle, applied control strategy and parameter design of proposed PET are introduced in detail.

This paper proposes a current and voltage control technique based on virtual synchronous generators (VSG) theory and passivity-based control (PBC) theory. Firstly, the basic topology and working principle of MMC-PET are introduced, and the mathematical models of …

Apr 25, 2024 · To verify the superiority of the passive super-twisting second-order sliding mode control strategy (PBC-SW-SOSMC) based on MMC-PET, we constructed a simulation model of MMC-PET and its control system on the MATLAB/Simulink (R2018b) platform.

Nov 29, 2020 · This paper introduces the characteristics of a novel single-stage power electronic transformer (PET) based on isolated modular multilevel converter (I-M²C). This new PET totally eliminates the individual DC-link capacitor in the traditional two-stage PET, which effectively reduces the number of the power electronic devices and the ...

May 10, 2024 · For a VSC-HVDC transmission system based on a hybrid topology converter of full-bridge and half-bridge, a kind of virtual synchronous generator (VSG) control strategy which can be applied to...

Abstract: This paper proposes a novel topology in the family of modular multilevel converter based power electronic transformers (MMC-PETs). Different from the existing MMC-PE Ts, an integrated switching pairs (ISP) is used as the new submodule of MMC, which is responsible for both the input and intermediate stages of PET.

This paper proposes a three-port power electronic transformer (PET) based on magnetic integration, where the modular multilevel converter (MMC) arm inductors and high-frequency transformer are ...
