“…Wide bandgap semiconductor switches, like GaN devices, offer the possibility of fast switching rates at low switching losses enabling new applications and improved efficiency. Among these new applications is the "talkative power" paradigm, combining power electronics and communication engineering [16]. The waveforms controlling the switches are simultaneously exploited for data transmission, dubbed wireline information and power transfer.…”

“…In the meantime, many other modulations have been proposed to reduce the switching losses, as in the case of soft switching [14], or to shape the harmonic spectrum, as in the case of random modulation [15]. The key observation motivating this paper is that the waveforms driving the switches can be simultaneously used for data transmission by modulating the ripple of the output voltage, as recently proposed by He et al [16]. They have dubbed the concept talkative power, and have verified the functionality by means of experimental results.…”

For the first time, the recently proposed "talkative power" paradigm combining power electronics and communication engineering is extended by channel coding and advanced receiver design aspects. In this concept, the pulses that control the duty cycle of switched-mode power converters are simultaneously used for data transmission by modifying the pulse phase, pulse frequency, pulse position or pulse width. The data sequence is embedded into the switching signal, similar to random modulation. The data can be used for example in point-to-point links, inside multi-port power converters, and for communication in networked power grids. As an application example a buck converter is studied. Its output voltage is numerically calculated for arbitrary two-level switching signals. The corresponding system model serves as a common framework for switching waveform design, receiver design, and performance analysis. The data sequence is represented by a small deterministic output voltage ripple. Various techniques to improve the data rate and the robustness of the communication are introduced, including line coding, a derivation of the optimum receiver in the sense of maximum-likelihood detection, and forward error correction coding as an option. Although emphasis is on a buck converter, the concept is applicable to other power converter topologies as well.

A laser beam is an effective power and data carrier that offers inherent advantages in terms of the simultaneous transfer of wireless information and power, which is widely used in both the Internet of Things and the Internet of Energy. This paper proposes an adaptive high-power and high-efficiency laser-based simultaneous wireless information and power transfer system. This is achieved through the use of adjusted and modulated laser diode systems at the transmitter and multiplexed photovoltaic cells, a coupler, a filter, and a maximum power point tracking (MPPT) converter at the receiver. The interaction between the converter and the communication component is investigated theoretically and experimentally using a current-fed boost MPPT converter with the MPPT algorithm of perturbation and observation. The results indicate a maximum DC output power of 7.3 W at the receiver and a maximum MPPT converter efficiency of 84%. Additionally, at a data rate of 495 kbit/s, with a DC output power of 5.11 W, the bit error ratio is 2.62 × 10 -4 for the binary amplitude shift keying modulation format, the MPPT converter efficiency is 88%, and the corresponding loss of communication is about 1% of the total transmitted power.

Both energy and information are different manifestations of light. Using light to offer the coexistence of sensing, communication, and energy harvesting functionalities, monolithically integrated III‐nitride diode system toward the Internet of Things is dealt with. The III‐nitride receiver is capable to convert optical signals into electronic ones and forward them to the transmitter. The energy harvester generates electricity from light to turn on the transmitter, which, in turn, can transmit information optically to other proximally located devices for analysis or relay the data over longer distances. This monolithic III‐nitride optoelectronic system can simultaneously achieve wireless energy harvesting and communication through light. The truly self‐powered, integrated III‐nitride system is a paradigm change where the previously competing sensing, communication, and energy harvesting operations can be jointly implemented on a single chip.
