Abstract
Examples relate to communicating synchronization information from a satellite to a power supply device to enable time synchronization between the satellite and the power supply device. The power supply device includes a port to receive, from a modulator, a modulated current corresponding to a power consumption across a dummy load, where a level pattern of the modulated current indicates the synchronization information received from the satellite. The power supply device includes a power consumption analyzer configured to receive a modulated voltage, across a shunt resistor, corresponding to the modulated current and recover, from the modulated voltage, the synchronization information.
Claims16
A power supply device comprising:
- a port to receive, from a modulator, a modulated current corresponding to a power consumption across a dummy load, wherein a level pattern of the modulated current is indicative of synchronization information received from a satellite;
- and
- a power consumption analyzer configured to receive a modulated voltage, across a shunt resistor, corresponding to the modulated current and recover, from the modulated voltage, the synchronization information to enable synchronization between the satellite and the power supply device based on the synchronization information.
An electronic system comprising:
- an electronic device comprising:
- a receiver to receive a signal including synchronization information from a satellite and generate a pulse signal based on the synchronization information;
- a modulator configured to receive the pulse signal from the receiver and generate a modulated current corresponding to a power consumption across a dummy load, wherein a level pattern of the modulated current indicates the synchronization information included in the signal;
- and
- a first port to receive the modulated current from the modulator;
- and
- a power supply device coupled to the electronic device via the first port comprising:
- a second port to receive, from the first port of the electronic device, the modulated current;
- and
- a power consumption analyzer configured to receive a modulated voltage across a shunt resistor corresponding to the modulated current and recover the synchronization information from a level pattern of the modulated voltage.
A method comprising:
- receiving, by a power supply device, a modulated current from an electronic device corresponding to a power consumption across a dummy load, wherein a level pattern of the modulated current is indicative of synchronization information included in a signal received at the electronic device from a satellite;
- and
- recovering, by the power supply device and from a level pattern of a modulated voltage across a shunt resistor corresponding to the modulated current, the synchronization information to enable synchronization between the satellite and the power supply device based on the synchronization information.
