Non-Volatile RF Reconfigurable Antenna on Flexible Substrate for Wireless IoT Applications

open access: yesIEEE Access, 2021
To date semiconductor switches are still the main enablers for electrical circuit and system reconfigurability. They however not only consume dynamic power but also dissipate static power, the former for performing on/off operation and latter for holding

Frequency-switched photonic spiking neurons

open access: yesOptics Express, 2022
We propose an approach to generate neuron-like spikes of vertical-cavity surface-emitting laser (VCSEL) by multi-frequency switching. A stable temporal spiking sequence has been realized both by numerical simulations and experiments with a pulse width of sub-nanosecond, which is 8 orders of magnitude faster than ones from biological neurons.

Power Transmission and Control in Microturbines’ Electronics: A Review

open access: yesEnergies, 2023
When the shaft rotates in microturbines, the rotational movement is converted to electrical power. This is achieved through a permanent magnet synchronous machine (PMSM) housed on the shaft and the power electronics components. To the best of the authors’

Comparison between unipolar and bipolar single phase grid-connected inverters for PV applications [PDF]

open access: yes, 2007
An inverter is essential for the interfacing of photovoltaic panels with the AC network. There are many possible inverter topologies and inverter switching schemes and each one will have its own relative advantages and disadvantages.
