Textile‐based sensors for electrical current measurement in three‐phase cables
IET Smart Grid, Volume 5, Issue 1, Page 1-11, February 2022., 2022 Abstract There is much discussion about the implementation and benefits of smart electricity networks. However, the reality is that the instrumentation needed at low voltage is too expensive for large‐scale deployment. The most highly used monitoring systems in use today are based on Rogowski coil technology, which can only be used on single‐phase ...

Development of a current source resonant inverter for high current MHz induction heating
IET Power Electronics, Volume 15, Issue 1, Page 1-10, 7 January 2022., 2022 Abstract High frequency industrial induction heating processes typically employ resonant inverters to reach high efficiency at high power levels. Advancements in wide band gap (WBG) device technology has made it feasible to push the possible frequency of these processes into the MHz regime using solid state technology. Several topologies can be applied,
