摘要： The present invention relates to a stackable connector for wireless transmission of power between separate devices comprising such a connector of a system, in particular of a patient monitoring system, said separate devices comprising such a connector. The connector comprises a housing (301, 407) and a magnetic coupling unit (302) arranged within the housing (301, 407) for transmitting power to and/or receiving power from another device of the system having a counterpart connector by use of inductive coupling. Said magnetic coupling unit includes a flux concentrator (303, 401, 411, 432, 442), at least part of which having a U-shaped cross-section forming a recess (304, 402, 412, 422, 437, 447) between the legs of the U, a first coil (305, 417, 431) arranged within the recess of the flux concentrator, and a second coil (306, 427, 441) arranged outside of the recess in which the first coil (305, 417, 431) is arranged. The housing (301, 407) is arranged to allow stacking of connectors upon each other so that the first coil (305, 417, 431) of the connector (300, 400, 410, 430) and a second coil of another connector stacked upon the connector together form a transformer for inductive power transmission there between and/or the second coil (306, 427, 441) of the connector (300, 400, 410, 430) and a first coil (305a) of another connector (300a) stacked upon the connector (300, 400, 410, 430) together form a transformer for inductive power transmission there between.

摘要： A switching control circuit alternately turns on/off, at a switching frequency at which the impedance of a multi-resonant circuit becomes inductive, switching elements with a dead time therebetween. In an operation in the third quadrant of current-voltage characteristics of the switching elements, the switching elements are turned on by supplying a control signal to control terminals of the switching elements, and a dead time is determined so as to satisfy tc≦td

摘要： The invention relates to a method for charging a vehicle battery by induction from a charging device including a charge transmitter including a primary coil L1 and an inverter capable of supplying the primary coil L1 with an AC supply voltage E. Said device also includes a charge receiver including a secondary coil L2 arranged in a vehicle. Said method consists of adjusting a frequency f of the power supply voltage (E) to the resonance frequency fo, when a motor vehicle is located in a parking space. Said method comprises the following steps: setting a first power-transmission parameter (E, f); starting an iterative test which consists of: setting a value of a second power-transmission parameter (E, f); varying the second power-transmission parameter (E, f) in a second authorized adjustment range; measuring the power (Pbat) transmitted between the charge transmitter and the charge receiver; determining if the power (Pbat) is no lower than a predetermined operating threshold (PObj); determining if the power (Pbat) increases; ending the iterative test if the transmitted power (Pbat) is higher than the predetermined operating threshold (PObj); setting the power supply voltage (E) in order to reach the measured transmitted power (Pbat), said first and second transmission parameters being set to the previously established value thereof.
