4 COMMUNICATION OVER A VOLTAGE ISOLATION BARRIER US14836424 2015-08-26 US20160065398A1 2016-03-03 Anthony B. Candage; Aswath Krishnan Krishnamoorthy
A transmitter circuit comprises: an input, an encoder circuit, and a transmitter. During operation, the transmitter circuit receives an input signal. The encoder circuit encodes the received input signal into an encoded signal. The encoder circuit produces the encoded signal: i) to indicate changing states of the input signal, and ii) to include a supplemental transient signal with respect to the received input signal. The transmitter transmits the encoded signal from an output of the first circuit over a link to a second circuit such as a receiver circuit. A receiver decodes the encoded signal to reproduce a rendition of the input signal to control remote power supply circuitry. Presence of the supplemental transient signal in the encoded signal indicates to the receiver circuit that the first circuit actively transmits the output signal even though there may not be any change to a current state of the input signal.

The present invention includes a solution to the adherence to and improvement of the specifications regarding the conducted susceptibility of a microwave chain. It has an advantage of enabling significant attenuation of parasitic modulated signals carried in microwave chains of microwave devices such as those that are integrated into satellites by adding one or more 180° phase shifters between the units which do not exhibit a sufficient conducted susceptibility performance. The invention consequently makes it possible to do away with certain elements charged with the attenuation of the parasitic signals generally integrated into the power supplies and other DC/DC converters present in all contemporary microwave equipment.

PROBLEM TO BE SOLVED: To ensure zero point offset by providing 1st, 2nd, 3rd switching period sets and connecting the 2nd and 3rd switching period sets to an auxiliary amplifier to relate even the auxiliary amplifier to a zero point of an amplifier. SOLUTION: First switching period sets S11 , S12 S1 N connect N-sets of signal channels L1 , L2 , LN to one input of an amplifier 1 so as to relate the amplifier 1 to a circuit zero point SN. Second switching period sets S21 , S22 , S2 N are used to connect further N-sets of channel zero point lines N1 , N2 , Nn . Thus, inputs of third switching period sets S31 , S32 , S3n connected to inputs of the sets S21 , S22 , S2n and outputs are connected in common to an auxiliary amplifier 3. The amplifier 3 is related to the circuit zero point SN similarly to the amplifier. The potential at the zero point SN of a 1-out-of-N multiplexer 2 is applied to each multiplexer of the lines N1 , N2 , Nn .
18 DISPOSITIF ELECTRONIQUE DESTINE A DES EQUIPEMENTS HYPERFREQUENCES EMBARQUES SUR SATELLITE EP08872901.7 2008-12-16 EP2248254A1 2010-11-10 IBERT, Christophe; DEBARGE, Cécile
The present invention provides a solution for maintaining and improving the specifications of the conducted susceptibility of a microwave channel. The main advantage of the invention is to provide a significant attenuation of the parasite modulated signals (PAR4) conveyed in the microwave channels of microwave devices such as those integrated into satellites, by simply adding one or more 180° phase shifters (PHI) between the components (CRF1,CRF2) that do not have a sufficient conducted susceptibility performance. Consequently, the invention makes it possible to omit certain elements in charge of attenuating parasitic signals and generally integrated in the power supplies and other DC/DC converters (ALIM1) present in all current microwave apparatuses.
