In the centre tapped rectifier: It seems as if the highlighted ground line would provide a short circuit for any current developed between the top/bottom wires and the centre tap, eliminating
The answer is not a straightforward yes or no. This article explores the benefits and drawbacks of grounding DC power supplies. DC power supplies are a common, perhaps almost guaranteed, component of any control system, especially one containing a digital controller.
The best way to minimize the possibility of creating voltage differences in your system grounding is to use ground planes via chassis and frame connections. Since the source of the high voltage current is the power supply, it is recommended that it be the tie point for system grounds to other external devices.
So, the short answer for some 24V DC systems is no, the output is not required to be connected to ground. From the UL 508A specification, there are further answers that also dictate grounding depending on the input voltage of the power supply. Figure 1. Grounding power supplies inside a control cabinet can be a difficult decision.
The first, and perhaps most obvious benefit of grounded DC output is the safety protection element. Consider a wire running from the -V output wire to the earth ground system via a green wire.

Should you connect a DC power supply to ground or not? The answer is not a straightforward yes or no. This article explores the benefits and drawbacks of grounding DC power
To protect against lightning, rectifier transformers should be equipped with lightning protection devices, such as surge arresters. Surge arresters are designed to divert the high-energy
How do you ground a power supply? Ground the negative terminal of the power supply unless using an internally grounded power supply or a floating system (subject to Electrical Engineer approval).
The rear panel of the power supply should be connected to this system ground in the most direct, stout manner possible, using the heaviest gauge wire available, connected in a secure and durable
Hi, I''m halfway through making a simple dual power supply for home use (5.5 - 15.5VDC; approx. hopefully 0.75A max. but probably only 0.5A at most to avoid frying a TO220 linear regulator
