English Abstract
This article introduces the principles of the talkative power converter/conversion (TPC) in an ac system, demonstrated through its application in a three-phase power factor correction (PFC) in a variable speed drive (VSD) system. It outlines the mechanism of signal spectrum shift in ac systems, especially those formed by power electronics inverters, and highlights TPC’s broader applicability beyond dc systems. The challenges of baud rate limitations and high bit error rates are addressed with data transmission enhancement through topology and communication side. Both simulations and experiments affirm the practicality and effectiveness of the proposed TPC scheme in the field-oriented control for a VSD, demonstrating high-performance results with a feedback communication rate of 10 kb/s. The broader impact of this research lies in its potential to simplify communication in various ac applications, contributing to advancements in power systems and VSD technologies.
