Abstract
This paper presents the electromagnetic interface (EMI) impact on the current transformer with amorphous HB1-M core, printed circuit board (PCB) power transformer and the filter of inductor for Internet of Things (IoTs) device. According to the antenna principle, the radiation emission power responses of PCB transformer and current transformer are estimated and found to be negligible due to the EMI experimental report. Based on this reason, consideration of the amorphous core in design manufacturing and EMI filter development is indispensable. Thus, the current transformer of amorphous HB1-M core is annealed at 350°C and soaked for 1.5 h. The simulation results of electromagnetic field show an EMI impact on filter performance. EMI frequency between 50 to 400 MHz for filter is found to be suitable for PCB. Experimental results have confirmed that the application of PCB transformer with HB1-M would be performed as well in high permeability and sensitivity. Key words: Internet of things (IoTs), electromagnetic interface (EMI), soft magnetic sensor.
Highlights
Internet of things (IoTs) is the network of devices, and recent research proposed a performance degradation of Internet of Things (IoTs) communications in smart cities by using a new routing algorithm to improve them
This study has figured out an algorithm defined as smart and self-organised routing algorithm (SSRA), which can be selected as the best route for the packets and for which SSRA can be extended to the devices lifetime by parameter of fair and efficient energy consumption (Hamrioui et al, 2018)
The design of practical electromagnetic interface (EMI) filter of varistors is based on the selection of an appropriate core and winding configuration
Summary
Internet of things (IoTs) is the network of devices, and recent research proposed a performance degradation of IoTs communications in smart cities by using a new routing algorithm to improve them. This study has figured out an algorithm defined as smart and self-organised routing algorithm (SSRA), which can be selected as the best route for the packets and for which SSRA can be extended to the devices lifetime by parameter of fair and efficient energy consumption (Hamrioui et al, 2018). Due to this reason, the IoTs growing popularity is gaining more attention as the security and sensitivity problem in IoTs device applications and sensor-based threats to IoT devices is developed. Development of electronic circuit to surround electromagnetic signal impact on the device is not measured
