IEEE transactions on power electronics, 2023
A solid-state transformer can directly convert medium voltage to low voltage (e.g., 400 V) with minimized power-conversion stages. The transformer in the dc–dc module not only provides medium-voltage insulation but also significantly affects the power ...

Matrix Converter-Based Active Distribution Transformer
IEEE Transactions on Power Delivery, 2016This paper proposes a matrix converter-based active distribution transformer (MC-ADT) with enhanced control functionalities to be used in smart grids (SG). The proposed MC-ADT uses a matrix converter (MC) connected to a transformer inserted in series with the grid, and allows: 1) real-time voltage regulation of the low-voltage side of the MC-ADT, based

2010 Conference Proceedings IPEC, 2010
The Y/Y phase C converter transformer in ±500kV Zhaoqing converter station had been seriously damaged, because the 1.1 bushing had interior flashover. Due to it will take almost one year to remedy it or to manufact a new transformer, in case of that the transformers in Zhaoqing converter station fall to malfunction, this paper study the feasibility of ...

Using convert to transform source code
Software: Practice and Experience, 1979AbstractThere are a number of reasons why one might wish to transform the source code of an operational program: To make the program conform to a standard layout. To make the program conform to syntax and semantics standards. To improve the performance of the program.
