A Primary Side CCS-MPC Controller for Constant Current/Voltage Charging Operation of Series-Series Compensated Wireless Power Transfer Systems

Due to the climate change, electrification of the transport fleet must be done much faster. Dynamic wireless charging (DWC), eliminates waiting time for charging electric vehicles (EV), increases the range of motion, reduces the size of li-ion battery and automates the charging process. In the DWC method, an EV may pass on the charger pads (transmitter) at maximum speed, and this may happen several hundred times a day. So, the charger must have quick and smooth transient response, applying the proper charging strategy to the battery. In this paper, a WPT system by continuous control set model predictive controller (CCS-MPC) can achieve a very fast and smooth transient with constant current/ voltage (CC/ CV) charging strategy. The proposed controller is simple, fast and based on optimal strategy. In addition, with the aim of eliminating the communication link, the output load is estimated, therefore system stability and simplicity is guaranteed.
