“…Couplers, amplifiers and auxiliary modulators are not necessary in this concept. In subsequent publications, additional types of power converters [22]- [26], various modulation schemes [27]- [31], coding aspects [29], [32], multiuser aspects [33], [34], voltage control [35] and further applications [36]- [38] have been investigated, and surveys & tutorial [39]- [41] have been conducted. The terms power talk and talkative power were coined independently of each other in [33] and [39], respectively.…”

This article presents a STEM learning platform focusing on renewable energy generation, energy storage, and simultaneous transmission of energy and data. These enabling technologies are classified already by teenagers as authentic, multidisciplinary, sustainable and future-oriented, which helps to stimulate their interest. Linking electric energy generation/storage/consumption and information transfer is done through the innovative concept of talkative power conversion. Students are not only provided with meaningful background information on the topics under investigation, but they also learn how to implement these concepts on a mixed hardware/software platform, which increases their motivation and understanding of STEM topics. The learning platform elaborated in this article is suitable for pupils at high school as well as undergraduate and graduate students in electrical engineering and related fields, since the level of difficulty is adjustable. Experiments are exemplified at a level suitable for undergraduate students in electrical engineering and information technologies after two years of study.

“…TPC can be divided into RS-TPC and CS-TPC as shown in Fig. 4(a) and (b) [14], [15], and hybrid combinations thereof [12]. RS-TPC embeds information via superposition of data on the reference voltage, while CS-TPC modifies the carrier signal for this purpose.…”

“…TPC has been called zero-additional-hardware PLC in [9]. Other researchers have called it from the signal perspective such as Power & Signal Multiplex Transmission (P&SMT) [10], Power and Signal Synchronous Transmission (PSST) [3], and Power/Signal Dual Modulation (PSDM) [11], [12]. Nonetheless, none of these definitions is wide and precise enough to be taken into account for PLC and Simultaneous Wireless Information and Power Transfer (SWIPT) while fulfilling the concept of power conversion, transmission, and distribution.…”

Power Line Communication (PLC) and Simultaneous Wireless Information and Power Transfer (SWIPT) are popular examples of applications, where power and information are transmitted simultaneously. In most cases, different devices have been used to generate the power and communication signals independently. Usually, the information is superimposed onto the power signal using an external modulator. Recently, power converters have been used to generate pulses not just for power conversion but also for information transfer simultaneously. This approach represents a fundamental difference because it exploits the signal processing potential of Pulse Width Modulation (PWM), where for power conversion only the average pulse width is used, while the information is represented by the harmonics instead of being filtered out, as typically done in power electronics. The concept of embedding information into the switching ripple generated by a switched-mode power converter has recently been dubbed Talkative Power (TP), in this paper referred as Talkative Power Conversion (TPC). TPC technologies are reviewed in non-isolated and isolated converters in this paper. Potential applications include visible light communications, battery management systems, switching reluctance generators/motors, microgrids, and wireless electric vehicle charging stations. Finally, trending topics are identified.INDEX TERMS Talkative power conversion, pulse width modulation converters, power line communication, switching ripple communication, simultaneous wireless information and power transfer.
