| Abstract |
An electric vehicle (EV) drivetrain integrated auxiliary battery charger is presented, eliminating the need for a separate auxiliary converter. Energy for the auxiliary battery is harvested from the switching ripple existing within the drivetrain. The topology adds a medium frequency isolation transformer, an LC resonant tank and a diode rectifier to a dual wound synchronous machine drivetrain, a drive common for medium and heavy duty vehicles (MHDV). The proposed topology allows auxiliary battery charging without interfering with the drivetrain operation. A 984W, 200V/12V experimental concept validation is provided. |
