摘要： A method for detecting a foreign object between a transmission pad and a reception pad for wireless power transfer (WPT) may comprise steps of performing a zero phase angle (ZPA) control for a power transfer converter included in or connected to the transmission pad; detecting a characteristic parameter with respect to at least one of an input current and a switching frequency of the power transfer converter; and determining whether or not a foreign object exists between the transmission pad and the reception pad according to whether the characteristic parameter with respect to at least one of the input current and the switching frequency deviates from an allowable range.

摘要： A method for detecting a foreign object between a transmission pad and a reception pad for wireless power transfer (WPT) may comprise: performing, by a processor, a zero phase angle (ZPA) control for a power transfer converter included in or connected to the transmission pad; detecting, by the processor, a phase difference between an input current and an input voltage of the power transfer converter; and determining, by the processor, whether or not the foreign object exists between the transmission pad and the reception pad by comparing the phase difference with a reference value.

摘要： A method for performing switching synchronization of a bridgeless rectifier in an electric vehicle (EV) wireless power transfer system may include receiving, by an EV control module, an input voltage of a transmission-side resonance circuit from a transmission-side of the EV wireless power transfer system; calculating, by the EV control module, a phase difference between the received input voltage and a voltage or a current selected in the bridgeless rectifier and a reception-side resonance circuit; and controlling, by an EV control module, switching time points of switches included in the bridgeless rectifier to decrease the calculated phase difference. The reception-side resonance circuit may be electromagnetically coupled to the transmission-side resonance circuit, and the bridgeless rectifier may be configured to rectify an output of the reception-side resonance circuit and to output the rectified output.

摘要： A method for controlling wireless power transfer to an EV using a bridgeless rectifier may include detecting a phase difference between an input voltage of a transmission-side resonance circuit and an output voltage of a reception-side resonance circuit; after detecting the phase difference, predicting a resonance frequency change direction according to a preconfigured design condition; and controlling switching time points of switches included in the bridgeless rectifier in a direction compensating for the predicted change direction.

摘要： A method for selectively performing a full bridge control and a half bridge control in a WPT system using an LCCL-S resonant network may include: performing the full bridge control by controlling the switches not connected in series of the full bridge inverter to operate simultaneously; calculating a coupling coefficient of the WPT system; determining whether it is possible to switch the full bridge control to the half bridge control based on the calculated coupling coefficient; in response to determining that it is possible to switch the full bridge control to the half bridge control, calculating a load of the WPT system; and performing the half bridge control for the full bridge inverter based on the calculated load.
