摘要： Data is communicated. In accordance with one or more example embodiments, a communications circuit communicates a digital data signal using a carrier signal having a frequency that is different than the frequency of the data signal. The communications circuit includes first and second sets of capacitors, a first circuit and a second circuit. The first circuit generates mixed data signals respectively mixed with the carrier signal and an inverse of the carrier signal, generates mixed inverted data signals respectively mixed with the carrier signal and an inverse of the carrier signal, provides the mixed data signals to the first set of capacitors, and provides the mixed inverted data signals to the second set of capacitors. The second circuit recovers the data signal from the mixed signals.

摘要： A controller (302) for an additional voltage converter, wherein the additional converter receives current from a main resonant converter. The controller is configured to provide a switch control signal for controlling a switch (312) of the additional converter. The controller comprises a first input configured to receive a first input signal (324) representative of a signal in the main resonant converter, and a delay component (332). The controller (302) is configured to determine when the first input signal (324) exceeds a zero value, and provide a signal to the delay component (332). The delay component (332) is configured to provide a switch control signal to the additional voltage converter such that the switch of the additional converter is operated after the expiry of a delay after the first input signal exceed a zero value in order to start a conduction period of the additional converter.

摘要： An isolated power supply comprises an input side and a transformer for transforming the input side power supply signal and providing it to an isolated output side. A single isolated transducer transmits control data between the input and output side or vice versa and optionally also in full duplex fashion, using a single data stream which can comprise multiple independent data sub-streams. These can be multiplexed data sub-streams channels and/or simultaneous bidirectional sub-streams.
