A packet energy transfer (PET) receiver comprising receiver front-end circuitry including an input, an output, and at least one switch connected at the output. There is receiver output control and conditioning circuity including an input and an output to be connected to an electrical load. There is a synchronizer circuit to close the switch to allow power to flow into the receiver output control and conditioning circuitry during each of the first plurality of transfer periods of the transmitter and to open the switch to prevent power to flow into the receiver output circuitry during a first plurality of sample periods. There is a load controller that disables the synchronizer circuit and operates the switch to close it and allow power to flow into the receiver output control and conditioning circuitry during subsequent transfer periods and to open the switch to prevent power to flow during a subsequent sample periods.

Hot pluggable packet energy transfer receiver

A set of packet-energy-transfer operating parameters is automatically configured to optimize safety, efficiency and/or resiliency in a digital-electricity power system. A set of limits is configured for packet-energy-transfer operation that does not immediately preclude safe operation of the transmission lines, wherein each limit in the set defines constraints for at least one of measurements and calculations based on impedance in series or in parallel with the transmission lines, operational efficiency of the digital-electricity power system, and/or voltage or current signal integrity. The operation of the transmission lines is measured, and the measurements are compared with the limits. Upon at least one of the limits being exceeded, a revised set of limits is automatically configured (or a new configuration is generated) based on which limit was exceeded. The measurements, comparison, and reconfiguration are repeated until an acceptable range of operation is identified or until a predetermined time limit is exceeded.

Methods for automatic ranging of digital electricity operation

The integrity of transmission-line voltage measurements in a digital-electricity power system in the presence of line-voltage disturbances during a sample period is ensured via detection or prevention by (a) acquiring at least three measurements of transmission-line voltage, performing numerical analysis on the measurements to produce a polynomial function, and estimating accuracy of the polynomial function based on magnitude of variance of the individual measurements; (b) applying a negative or positive bias to the transmission line during the sample period and acquiring voltage measurements to determine a rate of voltage change with the bias applied; (c) shifting a start time of a first sample period on a first transmission line in reference to a second sample period on a second transmission line to reduce overlap of sample periods across both transmission lines; and/or (d) synchronizing start times of respective sample periods on first and second transmission lines.
