Simulation Model of Un interruptible Wireless Power Supply Based on Single-Phase Matrix Converter with Active Power Filter Functionality

This paper presents simulation model of Uninterruptible Wireless Power Supply (UWPS) using a Single-Phase Matrix Converter (SPMC) topology with active power filter (APF) functionality. In this work, the SPMC topology is used to operate as both inverter and rectifier operations to perform the proposed Uninterruptible Power Supply (UPS) using a single circuit configuration. The DC voltage of the UPS is then supplying to the load wirelessly using the Wireless Power Transfer (WPT) circuit, thus, achieving the aim of the proposed system to supply continuous and conditioned power to the DC load wirelessly. The proposed UWPS system using SPMC has achieved a power transfer efficiency of higher than 90%. In addition, the use of SPMC topology to perform both rectifier and inverter operations can reduce the number of power conversion stages, hence, improving the power density of the power supply system. A simulation model using MATLAB/Simulink was developed, and selected results are presented to verify the proposed system.
