Improved Efficiency of Two‐Stage Partial Power Processing Architectures for Inductive Power Transfer
This paper proposes a high‐efficiency two‐stage inductive power transfer (IPT) system with partial power processing to reduce energy losses in conventional cascaded architectures. By processing only partial power through the DC/DC converter, the system minimizes losses, lowers component stress, and improves power density.

Research on Full‐Duplex Data Transfer Simultaneously Based on Wireless Power System
The power transfer of the proposed system uses a bilateral LCC‐type high‐order compensation network. The data injecting circuit (TX1 and TX2) is connected in series to the power circuit through the data coupling transformers Tdt1 and Tdt2, and the data extracting circuit (TR1 and TR2) is connected in parallel to power coils.

The arm‐multiplexing modular multilevel converter (AM‐MMC) is a lightweight, high‐power‐density topology whose conventional modulation strategies require large circulating currents to maintain energy balance. This paper establishes a time‐domain analytical model of the AM‐MMC energy‐balance mechanism and proposes an optimised independent arm modulation
