Abstract: Disclosed is an immersed cabinet, which includes a cabinet body and a heat sink assembly, wherein the heat sink assembly is in sealed connection with the cabinet body and configured to seal an opening of the cabinet body. The cabinet body accommodates a plurality of devices to be cooled, and cooling liquid is put in the cabinet body and used for immersing the plurality of devices to be cooled. The cooling liquid absorbs heat generated by the plurality of devices to be cooled and then is vaporized. The heat sink assembly exchanges heat with the vaporized cooling liquid, so that the vaporized cooling liquid condenses and flows back to the cabinet body for circulation, and the heat sink assembly dissipates the heat into the atmosphere. Therefore, the heat dissipation structure design of the immersed cabinet is effectively simplified.

Abstract: A method for operating a wireless charging transmitter includes switching, by the wireless charging transmitter, an operating mode of a full bridge inverter of the wireless charging transmitter from a first mode to a second mode; and changing, by the wireless charging transmitter, an operating point of the wireless charging transmitter from a first operating point associated with the first mode to a second operating point associated with the second mode, the second operating point being selected to dampen a change in a rectifier voltage of a wireless charging receiver inductively coupled to the wireless charging transmitter.

Abstract: A method for modulating a signal including operating a circuit in a first arrangement during a first operating interval and switching the circuit between the first arrangement and a second arrangement during a first modulation interval to vary a load on the circuit to produce a first amplitude shift keying (ASK) signal. The method further includes detecting a voltage on the circuit crossing a threshold level and operating the circuit in the second arrangement during a second operating interval. The method also includes switching the circuit between the second arrangement and the first arrangement during a second modulation interval to vary the load on the circuit to produce a second ASK signal.
