摘要:
A vehicle propulsion (100) includes an alternating current (AC) traction drive (147), a first energy storage system electrically coupled to the traction drive through a direct current (DC) link (114), a second energy storage system electrically coupled to the traction drive such that the voltage output from the second energy storage system is decoupled from the DC link using a bi-directional boost converter (120), and an energy management system configured to control said first and second energy storage systems when the vehicle is operating in at least one of a pre-charge mode and a normal operation mode with the traction drive system (147) enabled.

摘要:
A method 200 for determining rotor position comprising sending a signal to a stator 102, receiving a first signal indicative of a first estimated stator inductance, and receiving a second signal indicative of a second estimated stator inductance. The method further includes, calculating a first rotor position angle using a function including the first estimated stator inductance and the second estimated stator inductance.
