Abstract: Systems and methods for operating a power system having a doubly fed induction generator are provided. In example implementations, an electrical power system (100) connected to a power grid (190) can include a generator (120) comprising a stator and a rotor, the stator connected to the power grid via a stator power path, and a power converter (130). The power converter (130) can include a line-side converter (134) coupled to the power grid (190) via a converter power path and a rotor-side converter (132) coupled to a rotor bus (124) of the rotor and the line-side converter (134) via a DC link, the rotor-side converter (132) configured to convert a DC power on the DC link to an AC signal for the rotor bus (124). The power system (100) can also include an active filter (250) comprising one or more active controlled components, the active filter (250) being coupled in parallel with the rotor-side converter (132) to reduce harmonics of the electrical power system (100).

Abstract: An apparatus for use in a wireless power transfer system (100) that provides a first AC voltage (224) from a first converting unit (204) via a primary coil (228) of a contactless power transfer unit (208). The first AC voltage is managed by a control unit (206) coupled with a second transceiver (216). The apparatus comprises a secondary coil (230) configured to wirelessly receive an input power having the first AC voltage (224) from the primary coil (228) and provide the input power to a second converting unit (210). The second converting unit (210) is configured to receive the input power from the secondary coil (230) and to convert the first AC voltage (224) of the input power to an output DC voltage (238). The input power having the output DC voltage (238) is provided to an electric load (232). The apparatus comprises a first transceiver (214) configured to communicate a voltage signal to the second transceiver (216). The voltage signal is representative of the output DC voltage (238) across the electric load (232). The voltage signal is communicated to cause the control unit (206) to regulate the first AC voltage (224) if the output DC voltage (238) across the electric load (232) is greater than a voltage reference value. The apparatus comprises a switching unit (212) configured to regulate the input power having the output DC voltage to protect one or more components of the apparatus.

Abstract: A wireless power transfer system is disclosed. The wireless power transfer system includes a first converting unit for converting a first DC voltage of an input power to a first AC voltage, a contactless power transfer unit for transmitting the input power having the first AC voltage, and a second converting unit for transmitting the power having a second DC voltage corresponding to the first AC voltage to an electric load. Additionally, the wireless power transfer system includes an active voltage tuning unit for controlling the second DC voltage based on a difference between the second DC voltage and a reference voltage and at least one among a difference between the resonant frequency and the constant operating frequency and a difference between a phase angle of the first AC voltage and a phase angle of an AC current.
