The heat exchanger is a three-medium heat exchanger with phase change material (PCM) stored in the external fin tubes. It allows the refrigerant flowing inside the internal fin tubes and the air to
Output Current Estimation and Control in Primary Side LCC Secondary Side Series Compensated Wireless
Wireless charging of electric vehicles require the ability to control the output current in the power transfer system, but that is often not possible as the availability of signals from the secondary side to the primary side is difficult and not always feasible.
This invention presents a multiport converter (MPC) based power supply to charge the 12 V and 24 V auxiliary batteries in heavy duty (HD) fuel cell (FC) electric vehicle (EV) power train.
