AI Customer ServiceYour first circuit won''t work because there is nothing in place to discharge the capacitors. There will be a current through the coil while the capacitors charge, then nothing once they''ve
AI Customer ServiceConnecting one end of your capacitor bank to ground (through a resistor or not) isn't going to discharge the caps. You need to connect the resistor across the caps for that to happen. To elaborate on @brhans comment, with the earth switch the circuit is fully isolated and floating with respect to ground.
When the switch closes to insert the second capacitor bank, the inrush current affects mainly the local parallel capacitor bank circuits and bus voltage. What would cause a Restrike when Switching Capacitors? grounded cct.
The output capacitor's ground-terminal voltage is important because the load, which is what requires the regulator's accurate output voltage, is usually placed next to the output capacitor—and thus we want the feedback to be referred to that particular part of ground. Figure 1.
The inrush current affects the whole system from the power source to the capacitor bank, and especially the local bus voltage which initially is depressed to zero. When the switch closes to insert the second capacitor bank, the inrush current affects mainly the local parallel capacitor bank circuits and bus voltage.
So for capacitors, if a capacitor is polarized (has a + and - node), then all you need is to make sure that the voltage at the + node is greater than or equal to the voltage at the - node. You do NOT have to connect the - node to ground. YOu still need a decent discharge path on that.
You need to connect the resistor across the caps for that to happen. To elaborate on @brhans comment, with the earth switch the circuit is fully isolated and floating with respect to ground. Adding the earth references one point of the circuit to ground but no current can flow because there is no return path for it into the circuit.
