Patent number: 10513187Abstract: A converter system for electrically driving a vehicle, including a grid-side converter, a DC link with at least a first and second potential conductors, and a motor-side converter. The motor-side converter allows a bidirectional flow of energy. The grid-side converter has a single phase on the input side and is connected to a supply grid. The grid-side converter is unidirectional and allows a flow of energy from the supply grid into the DC link. The DC link connects the grid-side converter to the motor-side converter and has a first electrical energy storage between the first and second potential conductors. The electrical energy storage is connected to the DC link via an electrical connection. The flow of energy from the DC link into the further electrical energy storage and the flow of energy from the further electrical energy storage into the DC link is able to be controlled.Type: GrantFiled: November 18, 2015Date of Patent: December 24, 2019Assignee: ABB Schweiz AGInventors: Beat Guggisberg, Beat Ronner

Patent number: 9843199Abstract: An exemplary inductive power transfer system having a transmitter coil and a receiver coil. A transmitter-side power converter having a mains rectifier stage powering a transmitter-side dc-bus and controlling a transmitter-side dc-bus voltage U1,dc. A transmitter-side inverter stage with a switching frequency fsw supplies the transmitter coil with an alternating current. A receiver-side power converter having a receiver-side rectifier stage that rectifies a voltage induced in the receiver coil and powering a receiver-side dc-bus and a receiver-side charging converter controlling a receiver-side dc-bus voltage U2,dc. Power controllers that determine from a power transfer efficiency of the power transfer, reference values U1,dc*, U2,dc* for the transmitter and receiver side dc-bus voltages. An inverter stage switching controller controls the switching frequency fsw to reduce losses in the transmitter-side inverter stage.Type: GrantFiled: March 30, 2015Date of Patent: December 12, 2017Assignee: ABB Schweiz AGInventors: Roman Bosshard, Johann Walter Kolar, Francisco Canales, Beat Guggisberg, Guanghai Gong, Bernhard Wunsch
