In this video I demonstrated how to connect two or more power supplies in parallel. It is best practice to use reverse polarity protection diode to protect power supplies from inter-source power supplies. I shared wiring with practical demonstration.Should a power supply be connected in parallel?It is preferred that both power supplies are of same type and part number. To provide protection against power supply short circuit, it is recommended to connect external diodes (ORing Diodes or Load share modules) when multiple power supplies are connected in parallel. See figure 3.
Can a supply be used in parallel?The answer is “no.” It depends on the design of the supply, the technique used to connect the supplies, and the reason the supplies are being used in parallel. The most obvious and simplest way to hope to put supplies in parallel is to simply tie their outputs together.
Why do designers connect power supplies in parallel?Designers connect power supplies in parallel to obtain a total output current greater than that available from one individual supply as well as to provide redundancy, enhance reliability, avoid PCB thermal issues and boost system efficiency.
Can a 10000 power supply be used in parallel?While the above is true for many power supplies, EA's 10000 series products allow the user to combine different power levels in parallel. The only requirements are that they must have the same voltage rating, and they must be the same family. Examples are pairing PSB with PSBE or PUB and PSI with PS or PU.
Does paralleling 3.3V rails increase power?You will not get the increased power from paralleling the 3.3V rails unless you get two power supplies designed to perform load-sharing, and will have additional connections between them to facilitate communication that enables such a feature. This is typically only seen in certain server PSUs and high-end DC/DC converters, and never ATX PSUs.
Can a parallel power supply be a topology?This topology can be successfully implemented but there are many considerations to ensure the efficiency of the configuration. For parallel configurations, power supplies with internal circuits are preferred as the internal circuits will improve the efficiency of the current sharing. If the po
