What is a parallel power supply?Parallel power supplies refer to a configuration where multiple DC power supplies are connected in parallel to increase total output current. Each power supply shares the current load, ensuring that no single unit is overloaded. Higher Current Output – Allows for increased power delivery by combining the output of multiple units.
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.
Should I use two power modules in parallel?Firstly, you may need more current than a single power module provides. Using two modules in parallel, the current to the load can be effectively doubled. Paralleling can also reduce the number of different power module types used, by meeting higher power requirements with lower power modules in parallel.
What is the maximum output power of a parallel converter?In the parallel configuration illustrated, the total output power is shared by the two converters. Since the power may not be evenly shared between the two converters, it is recommended to use converters that have maximum rated output power of around 75% of the max load power.
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.
Why do we need two DC/DC power modules?Designing such power systems is not straightforward, either – sometimes paralleling is the easier and quicker option. Also, using two smaller DC/DC power modules will spread the heat dissipated across a larger PCB area, helping reliability. A second reason is providing redundancy in high-reliability syste
