Should You Connect Grounds in a Power Supply?

Technical Consultant Zach Peterson is talking power and ground supplies today. How do you connect ground regions in a power supply, what’s the difference between isolated and non-isolated power supplies, and how do Y-Capacitors come into play? Zach covers all this and more.

Y-caps do not remove DC offset. They are just capacitors.
The special thing about Y-caps is that they are designed to fail open instead of failing short. This is ensure the the primary ground remains isolated from the secondary ground (using the terminology in the video) at DC and mains frequency – you don't want your USB wall wart applying mains voltage (120 or 240 V) to your USB cable if the cap fails. In this case the Y-cap returns the switching noise from the power supply to the USB ground so it doesn't radiate from the mains wiring since wall warts generally don't have a ground pin. There is a limit on the capacitance of the Y-cap so that the amount of AC main current it can pass is much less than 1 mA.
