Wireless Power Transfer in Electric Vehicles Using Single Phase Matrix Converter

In general, the current charging system still uses a plug-in system. The weakness of this technique is that it still uses a cable to connect the charger and the on-board battery, making it less efficient when used. The problem faced by electric vehicles is the possibility of running out of energy stored in the battery because of the absence of an electric energy charging station. The solution proposed in this study is to implement a wireless power transfer (WPT) system in the parking lot. This system is expected to charge batteries when the vehicle is stopped. The WPT topology used is resonant inductive power transfer with series-series compensation. Wireless charging (WC) technology is used to remove cables from electric vehicle charging systems. Because the driver and the charging system are not in direct contact, it can increase security when charging. The proposed system replaces the conventional two-stage AC/DC/AC converter with a single-phase matrix converter (SPMC) circuit topology. This topology is used to perform a direct AC/AC converter that changes the input voltage 311 volt at a frequency of 50 Hz to 85 kHz to fulfill switching operations on WPT systems. The WPT high-frequency output voltage is then rectified using an AC/DC converter into a DC form. To regulate the charging process developed, it will be equipped with a constant current constant voltage (CCCV) concept. The proposed research has been modeled and simulated using PSIM Software.
