Why do power supplies need to be connected in parallel?
Connecting power supplies in parallel is commonly used to increase the available output power or to provide system redundancy in the event of a power supply failure. The correct and reliable way to connect two or more power supplies in parallel is to have them equally share the load current.
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.
Which power supplies are suitable for parallel configuration?
EA-PSI 9000 Series – High-power bidirectional DC supplies capable of parallel configuration. Some power supplies include built-in current-sharing capabilities, ensuring that each unit contributes evenly. Tektronix’s Keithley 2260B Series includes automatic master-slave operation, simplifying the parallel setup.
What are the selection requirements of power supplies in parallel operation?
The selection requirements of power supplies in parallel operation are similar to those for redundancy, but the control function differs. It is obvious, in this type of application a single unit is not sufficient to provide desired power needs, so two or more power supplies in parallel are expected to be always loaded.
Can power supplies be connected in series?
Power supplies can be connected in series to increase the output voltage. However, only power supplies from the same product series and with the same rated output current should be used. The maximum load current should not exceed the smallest rated output current when selecting power supplies with different current ratings.
How do I Wire Load sharing with parallel power supplies?
Although there may be more than one way to wire load sharing with parallel power supplies, the star wiring method is typically the one most recommended. In the proceeding figures herein, it is demonstrated three typical star wiring schemes that provide options for any desired level of redundancy:
