Analysis on a Multi-Segmented Wireless Charging System for Mobile and Wearable Devices

Wireless charging technology has risen to prominence in recent years due to its potential to provide viable solution to the problems that are arising due to the usage of standard battery charging methods. In this paper, a single multi-segmented charging system is designed, which is capable to charge multiple devices at a time. The proposed charging system majorly holds three transmitter coils connected to single high-frequency power socket via relay units. Here, the major applications are mobile and wearable devices. Three transmitter and three receiver units make up the circuit. The circuit is mathematically analyzed and simulated results are extracted to understand the behaviour of the systems against load changes. The results of simulations of the suggested circuit architecture are provided. The circuit works with a wide variety of coupling coefficients and meets the power requirements of chosen application without the need for an additional communication module. The circuit’s operating frequency is maintained at 200 kHz, and it’s designed to provide efficient power to several devices. Here, two transmitter coils are designed for mobile devices and one is for wearable device. The detailed analysis of the proposed circuit is presented in this paper.
