Abstract
Techniques are provided to synchronize a remote power switch at a power receiver end of a power cable with a first power switch operation at a power source end of the cable, without any physical or data communication means for synchronization. This process may involve synchronization of a MOSFET-type switch with voltage pulsing at the power source cable end to a MOSFET-type isolation switch at the power receiver cable end to provide (voltage or load) power during the On-time and safety testing for a shock hazard during the Off-time. This method synchronizes switching pulses by sensing and synchronizing on the cable switching voltage transients from the source side. This method also involves blanking the additional switching voltage transients on the cable generated after the synchronized switching begins to maintain proper synchronization. These techniques may be used for a single-pair pulse power cable or with multi-pair multi-phase pulse power cables.
