grounding

I was wondering what are the disadvantages of floating ground (for example the chassis of a caravan) over earth ground. It's seems to be safer to left unearthed a chassis in order to break the grounding loop that exists in an electric shock event It is related to the electric potential of the...

I am building the Elenco AM/FM radio kit. And for a static power test it is telling me to connect my equipment ground to circuit ground test point 15 while the circuit is being powered by a 9volt battery. . I’m just pretty confused on what it means by “equipment ground” and what I can do to...

Noob alert! I'm tinkering on my garage project, standard vehicle stuff - 12V lead acid battery, 3-phase stator, reg/rec. I would like to put few additions to its circuit. Being a rookie, I'm not sure how to approach this correctly in terms of providing safe 5V for these microcontrollers. I've...

Hello - I'm creating an LED device and I'd like to have a good understanding of grounding/safety so I don't accidentally harm my users! I'm powering my device with an AC/DC wall mount adapter that outputs 20V which connects to a barrel jack on my PCB. I'm using an LED driver as well that...

I am designing a boost converter which is rated on 100 watts, 12 volts to 24 volts, switching frequency is 20 khz, in open-loop conditions. when I give the input power supply to the circuit as 12 volts, my driver (HCPL 4506 Mosfet Driver) will take VCC as 24 volts due to My microcontroller can...

I have Setup like this for my application. I have Transformer which gives out 12V 1A & 5V 500mA output.I have used isolated ADM2483 design where power galvanized isolated. Primary side 5v &gnd taken from 7805 regulator where 12v input comes from transformer. same ground used by MCU/ADM2483 side...

Hello everyone, Hope you are all doing fine. I have been facing an electrical issue in my house since last Christmas. When the lights or any appliance with motor in any room are turned off/on the TV would go out and come back ON in a short span (as if the power went out and came back in a...
