#102126 - Central ground star point Responding to: ???'s previous message |
Suresh said:
can it be connected directly to the centre tap of the transformer??..which grounds all other components that include relays and coils Your system should have a central ground star point, where the voltage regulators are sitting. All the various grounds can be connected to this central ground star point. To keep the ground return currents minimal, insert RLC-low-pass-filters in the according supply lines, or use at least decoupling capaitors. Do this next to the loads to keep the resulting current loops as minimal as possible. Use PCBs (printed circuit boards) containing a solid ground plane. This keeps the inductance for all ground returns current minimal and guarantees lowest possible ground noise. Kai |

| nope, you will be hanging at the noise m | 01/01/70 00:00 | |

| Possible, but... | 01/01/70 00:00 | |
