Abstract: A reliable fault detection and management system is described for providing safe high-voltage DC power delivery and distribution. The high voltage power delivery system provides a safer, more reliable, and easy-to-install power delivery system, while also providing for an RF communication link over a high-voltage single pair conductor cable.

Abstract: A system for the verification of the absence of voltage has a first series of resistors and a first voltage limiter connected between a power line and a first voltage sensor and such as to limit a sensed voltage to a set amount above a threshold set by a standard and a first series of LC resonance filters connected between the power line and a RF signal generator. The system also has a second series of resistors and a second voltage limiter connected between the power line and a second voltage sensor and a second series of LC resonance filters connected between the power line and an RF signal detector. The system is configured to detect continuity to the voltage line by sending an RF signal generated by the RF signal generator through the first lead line and detecting it at the RF signal detector via the second lead line.

Abstract: A high voltage pulse power delivery system is provided that includes dedicated safety features including fault detection and fault management. Alongside normal communications cabling, the pulse power delivery system provides remote power over standard multi-conductor cabling without dedicated conduit or separation. This simplifies installation of equipment, increases overall speed of deployment, and significantly reduces cost for deployment. The pulse power delivery system is further configured to transport power through a pulse current waveform.

Abstract: A permanently installed absence of voltage tester (AVT) may include a connectivity verification system for verifying the connectivity of system cable leads to the main power lines in electrical equipment. An installed AVT may indicate whether the electrical equipment is in an electrically safe state without first requiring direct access to the equipment. One step in the AVT test procedure may include connectivity verification by the connectivity verification system, which may include a sub-procedure to confirm that the installed AVT is directly coupled as intended with direct connection to the equipment being monitored. The connectivity verification system may validate that the AVT is measuring the actual voltage on the power lines of the electrical equipment and has not registered a no-voltage condition due to an unknown disconnection error or installation failure.

Abstract: In one embodiment, a power supply circuit has a power source, an inductor in series with a switching transistor connected to the power source, a pair of isolation capacitors connected across the switching transistor, a load connected to the isolation capacitors such that they isolate the load from low frequency energy from the power source, and a resonance circuit configured to amplify resonant ringing connected at least one of in parallel to the inductor or in parallel to the switching transistor.
