Buffering energy storage systems for reduced grid and vehicle battery stress for in-motion wireless power transfer systems

Номер: US20160001662A1
Принадлежит: UT Battelle LLC

An energy buffer including an electrochemical capacitor can be added to the primary circuit and/or to the secondary circuit of in-motion wireless power transfer system. The energy buffer(s) can smoothen the power delivered by the power grid and captured by a vehicle passing over an array of transmit coils through in-motion wireless power transfer. The reduction in the transient power transfer can reduce the peak current that flows through various components of the in-motion wireless power transfer system including a vehicle battery on the vehicle, and prolong the life of the in-motion wireless power transfer system.

Dc current controller for continuously variable series reactor

Номер: US20170077799A1

A direct current controller includes a rectifier configured to convert alternating current input into a direct current output. A converter electrically coupled to the rectifier generates a converted direct current voltage that regulates a converted direct current from the direct current output of the rectifier and synthesizes an ac component of an alternating current grid to counteract an induced back-emf. A direct current controller central controller coupled to the converter regulates the converted direct current.
