Mechanism and Suppression of Frequency-Decrease Effect Related to the Low Modulation Frequency Ratio in a High-Ratio MMC-Based DC Transformer

Chuyang Wang et al.

Summary: The high-ratio MMC-based DC transformer plays a crucial role in connecting different DC distribution networks. This study examines the frequency-decrease effect in the transformer, which has a similar structure to the typical MMC but different manifestations due to lower modulation frequency ratios. The study develops a theory to understand the mechanism of the frequency effect and provides a quantitative analysis. By redesigning the modulation strategy, the study eliminates the frequency-decrease effect and demonstrates the effectiveness of the proposed methods through simulations and experiments.

Impact of the Transformer Magnetizing Inductance on the Performance of the Dual-Active Bridge Converter

Shiyuan Yin et al.

Summary: This paper analyzes the operation and performance of the DAB converter with consideration of transformer magnetizing inductance, and shows that it impacts the soft-switching region, power transfer capability, and leakage inductor current. A simulation case study and experimental validation with a DAB converter prototype are provided to verify the analysis.
