Summary: This article proposes a novel power and signal dual modulation (PSDM) scheme that combines the control of three degrees of freedom to improve the bitrate. The feasibility of the scheme is shown by examining the compatibility between the different degrees of freedom. A practical scheme is then determined based on the analysis of signal carriers with different frequencies and the upper limit of M-ary modulation. Finally, an experimental prototype demonstrates the correctness of the proposed scheme and the theoretical analysis.

Summary: Electric power lines have the potential to create a widespread wired communication network, connecting electrical loads, power meters, and other devices. However, noise, signal attenuation, and unknown line impedances complicate power line communication (PLC) in practice. This article presents instrumentation that characterizes and verifies line characteristics for PLC applications, allowing for verification and adaptive tuning of PLC systems. Field experiments demonstrate reliable communication in challenging environments where conventional PLC fails.

Summary: This paper proposes a new Power Line Communication modulation scheme suitable for low-bandwidth communication, using a chirp spread spectrum physical layer similar to LoRa. The study shows that stable communication can be achieved even in channels with extreme multipath interference, impulsive noise, and low SNR. Compared to conventional LoRa, the synchronization requirements are relaxed. Simulations and experiments demonstrate the effectiveness of the scheme in providing load data from LV feeders back to the MV primary substation.

Summary: This letter proposes a PWM scheme based on phase-shift modulation for the 4P-IPOS converter. It investigates the operation with a dual-output configuration and achieves natural output voltages and inductor currents balancing without any extra components or dedicated control. The suggested scheme improves performance compared to the conventional PWM scheme, reducing input current ripple significantly at high voltage gain. An 800-W prototype of the 4P-IPOS converter was built and tested to verify its performance.
