Abstract:
A DC-DC converter includes a power oscillator connected to a first transformer winding, and a channel conveying a data stream through galvanic isolation by power signal modulation. A rectifier rectifies the power signal to produce a DC voltage. A comparator produces an error signal from the DC voltage and a reference voltage. An analog-to-digital converter converts the error signal to a digital power control value. A multiplexer multiplexes the digital power control value with the data stream to obtain a multiplexed bitstream. A transmitter driven by the multiplexed bitstream performs amplitude modulation of the power signal at a second transformer winding. A receiver connected to the first winding demodulates the amplitude modulated power signal. A demultiplexer demultiplexes the data stream and the digital power control value. A digital-to-analog converter converts the digital power control value to an analog control signal for the power oscillator.

Claim (Index 1):
A galvanically isolated DC-DC converter circuit, comprising:\n a power oscillator connected to a first winding of an isolation transformer forming a galvanic isolation barrier across which a power signal is transmitted, said galvanic isolation barrier further supporting a data communication channel on which a stream of data is conveyed by modulation of the power signal; a first transmitter configured to amplitude modulate the power signal at a second winding of the isolation transformer in response to a multiplexed bitstream; a rectifier connected to the second winding of the isolation transformer and configured to obtain an output DC voltage by rectification of the power signal at the second winding; a comparator configured to compare the output DC voltage to a reference voltage value and produce a voltage error signal; an analog to digital converter configured to convert the voltage error signal to a digital power control value; a multiplexer configured to multiplex the digital power control value with the stream of data to generate the multiplexed bitstream which is applied to the first transmitter; a receiver connected to the first winding and configured to demodulate the amplitude modulated power signal at the first winding; a demultiplexer configured to demultiplex the stream of data and the digital power control value; and a digital to analog converter configured to convert the digital power control value to an analog control signal to be supplied as a control voltage of the power oscillator for power regulation.
