Novel Zero-Sequence Blocking Transformer (ZSBT) Using Three Single-Phase Transformers

IEEE Transactions on Energy Conversion, 2013
Zero-sequence blocking transformers (ZSBTs), used to block the zero-sequence components that are present in a three-phase system, are commonly built winding the three phases around the same core limb. They are difficult to construct, especially in high-power applications that use large cross-sectional cables, as they require a symmetrical winding ...

Single-Source Three-Phase Multilevel Inverter Assembled by Three-Phase Two-Level Inverter and Two Single-Phase Cascaded H-Bridge Inverters

IEEE Transactions on Power Electronics, 2021
Multilevel inverters (MLIs) with reduced number of switching devices and dc sources have compact size, reduced cost, and higher efficiency. This article proposes a transformer-based single-source MLI with reduced number of components and small size ...

A Single-Stage Fault-Tolerant Three-Phase Bidirectional AC/DC Converter With Symmetric High-Frequency Y-Δ Connected Transformers

IEEE Transactions on Power Electronics, 2020
This article presents a single-stage isolated three-phase bidirectional ac/dc converter with symmetric Y-Δ connected transformers, which implements ac/dc buck conversion, high-frequency electrical isolation, and high power factor for ac side (PF > 0.99).

A Novel Methodology to Estimate the Nonlinear Magnetizing Characteristic of Single-Phase Transformers Using Minimum Information

IEEE Transactions on Power Delivery, 2022
This paper presents a novel methodology to estimate the saturation curve parameters of single-phase transformers, using minimum information from inrush and no-load tests.
