“…In the literature, optical fibers are applied to PECs in different sub-optimal ways, such as to command the gate drivers of the power devices, to sense their junction temperature, or to supply the gate drivers through power over wire in high voltage applications [2][3][4]. In all the reported cases, the optical link is used in a "one signal per fiber" manner.…”

The ubiquitous diffusion of Power Electronic Converters (PECs) in many fields of application including traction and energy conversion suggests the possibility of new and better integration of advanced power conversion and Information and Communication Technology (ICT) services. This work investigates the possible advancements in the use of optical communication links made of plastic optical fibers for control of PECs. The optical communication link connects the switching control to the converter control, following the line of separation between the expertise of power electronic and control engineers. Control wise, a PEC is a black box compatible with any off-board controller, now immune from the Electromagnetic Interference (EMI) produced by the power switches. The redundant optical link is ready for the high switching and sampling frequencies, made possible by relying on SiC power semiconductor devices (100+ kHz). Distributed control of multiple PEC units and advanced telemetry for diagnostics and prognostics are targeted. A proof-of-concept demonstrator is presented and tested. Moreover, the possible evolution towards a power electronic cloud with remote management and orchestration is described.

“…Fiber optic fiber Bragg grating (FBG) sensing technology has been emerging as a strong alternative that could provide solutions for advanced in situ sensing within electric machine geometries. Its inherent features of electromagnetic interference (EMI) immunity, small size, power passivity, flexibility, and ability to multiplex sensing provide opportunities to overcome many of the existing limitations with sensing used in electric machine CMs [10][11][12]. While FBG sensors are inherently responsive to mechanical and thermal excitation, they can be adapted to measure other physical phenomena of interest in electromagnetic rotary devices, such as through the integration of magnetostrictive material for magnetic flux measurement [13][14][15].…”

This paper presents a review of the recent trends and the current state of the art in the application of fiber optic fiber Bragg gratings (FBG) sensing technology to condition the monitoring (CM) and testing of practical electric machinery and the associated power equipment. FBG technology has received considerable interest in this field in recent years, with research demonstrating that the flexible, multi-physical, and electromagnetic interference (EMI) immune in situ sensing of a multitude of physical measurands of CM interest is possible and cannot be obtained through conventional sensing means. The unique FBG sensing ability has the potential to unlock many of the electric machine CM and design validation restrictions imposed by the limitations of conventional sensing techniques but needs further research to attain wider adoption. This paper first presents the fundamental principles of FBG sensing. This is followed by a description of recent FBG sensing techniques proposed for electric machinery and associated power equipment and a discussion of their individual benefits and limitations. Finally, an outlook for the further application of this technique is presented. The underlying intention is for the review to provide an up-to-date overview of the state of the art in this area and inform future developments in FBG sensing in electric machinery.
