I am confused about the ground part of a voltage converter.
This is a typical voltage converter. As you can see the the main voltage is 230V, and the output is 5V. Look at the output 0V, which is connected to the diode node, so I know, yes, this is the ground node.
Here also comes the question: As we know, for the main voltage power plug, especially in Europe or Asia, there is a ground line in the plug, so how I am going to do with the GND line in the main gate? Where is it in this circuit? There are just two lines input!
Also for Europe, there is only two inputs in the plug, but also, if you look carefully, there is actually a GND node in it.
If I simulate the main power voltage in the circuit by the sinusoidal source, how I am going to do that?
- One sinusoidal source power, one end is grounded, or
- Two sinusoidal source power, opposite connected, and the node between them is grounded
- Any other option?
