Should you ground a fancy, floating power supply or not?

WebFloating ground is a type of ground in which the ground doesn't have a physical connection to the earth; it simply serves as a type of 0V reference line that serves as a return path for current back to the negative side of the power supply. Circuits that aren't connected to earth ground must have a floating ground. Within the extent of the law provided by the NEC, the engineer has some flexibility on how each system can be designed or modified to meet their particular needs. Large systems with long wires often benefit from floating connections, as ground loops may be unavoidable, and voltage spikes are more common. … See more Before deciding on a grounded or floating system, system engineers should consult the NEC, as it dictates the legal standards for what and how different devices should be grounded or left ungrounded.

PCB Grounding Techniques: To Do and What Not To Do

WebWithout a reference to ground, the bus transceivers would be operating from a floating supply. Thus, current or voltage surges caused by lightning, ground faults, or other noisy environments would be able to lift the floating bus common to dangerously high levels. These events won’t destroy components connected to the bus, as their Webvoltage profile prior to the ground fault condition. The system will remain in this position until the fault is cleared, or another phase breaks down to form a double line-to-ground fault.
